To solve this problem we must use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration. The direction of the boat is northward and its magnitude is 1.633 m/s².

An object is said to be accelerated if there is a change in its velocity. The rate of change of velocity with respect to time is known as the velocity. It is a vector quantity and it has both magnitude and direction. It is the first derivative of velocity with respect to time.

Fx = 2200 [N]

Fa = 1350 [N]

F = √(Fₓ)² + (Fₐ)²

F = √(2200)² + (1350)²

F = 2581.18 N

Now using Newton's second law.

F = m×a

a = F / m

a = 2581.18 / 1580

a = 1.633 m/s²

Thus acceleration is 1.633 m/s² and it is northward direction.

the correct answer is ( head ) just took it

The body loses up to 40 percent of its body heat through the head area.

The heat transferred to the surrounding by the thermal conductive substance per unit time.

40 to 45 percent of human body heat is lost through the head and neck due to increased blood flow as compared to the rest of the body.

Along with the wrists and ankles, this can be 60 percent.

Thus, the body loses up to 40 percent of its body heat through the head area.

Explanation:

Answer:

Average Velocity = 120 mi/h

Explanation:

First we need to calculate the time taken by Connie to complete first half from Phoenix to flagstaff. So, we use:

s₁ = v₁t₁

where,

s₁ = distance from Phoenix to flagstaff = 180 miles

v₁ = speed of travel from Phoenix to flagstaff = 180 mi/h

t₁ = time taken to travel from Phoenix to flagstaff = ?

Therefore,

180 miles = (180 m/h)t₁

t₁ = 1 h

Now, we calculate the time for the return trip

s₂ = v₂t₂

where,

s₂ = distance from flagstaff to Phoenix = 180 miles

v₂ = speed of travel from flagstaff to Phoenix = 90 mi/h

t₂ = time taken to travel from flagstaff to Phoenix = ?

Therefore,

180 miles = (90 m/h)t₂

t₂ = 2 h

Now, we find total time:

t = t₁ + t₂

t = 1 h + 2 h

t = 3 h

and the total distance was:

s = s₁ +s₂

s = 180 mi + 180 mi

s = 360 mi

So, the average velocity will be:

Average Velocity = s/t

Average Velocity = 360 mi/3 h

Average Velocity = 120 mi/h

Answer:

A) Sue is lifting the bucket by a force of 49.035 newtons.

B) The bucket has an acceleration of 8.207 meters per square second on the Moon.

Explanation:

A) According to the First Newton's Law, a system is at equilibrium when it is either at rest or travelling at constant velocity. In this case, Sue must exert an external force on the bucket, whose magnitude is equal to the weight of the bucket but direction is opposed to it. By Second Newton's Law, we find that:

[tex]\Sigma F = F - m\cdot g = 0[/tex] (1)

Where:

[tex]F[/tex] - Lifting force, measured in newtons.

[tex]m[/tex] - Mass of the bucket, measured in kilograms.

[tex]g[/tex] - Gravitational acceleration, measured in meters per square second.

If we know that [tex]m = 5\,kg[/tex] and [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], then the lifting force is:

[tex]F = m\cdot g[/tex]

[tex]F = (5\,kg)\cdot \left(9.807\,\frac{m}{s^{2}} \right)[/tex]

[tex]F = 49.035\,N[/tex]

Sue is lifting the bucket by a force of 49.035 newtons.

B) By the Second Newton's Law, we have the following model:

[tex]\Sigma F = F-m\cdot g = m\cdot a[/tex] (2)

Where [tex]a[/tex] is the net acceleration of the bucket, measured in meters per square second.

If we know that [tex]F = 49.035\,N[/tex], [tex]m = 5\,kg[/tex] and [tex]g = 1.6\,\frac{m}{s^{2}}[/tex], then the net acceleration of the bucket is:

[tex]a = \frac{F}{m} -g[/tex]

[tex]a = \frac{49.035\,N}{5\,kg}-1.6\,\frac{m}{s^{2}}[/tex]

[tex]a = 8.207\,\frac{m}{s^{2}}[/tex]

The bucket has an acceleration of 8.207 meters per square second on the Moon.

(a) The force applied by Sue in lifting the bucket at a constant velocity is 49 N.

(b) The acceleration of the bucket when lifted on the moon is 8.2 m/s².

The given parameters;

The force applied by Sue in lifting the bucket at a constant velocity is calculated as;

[tex]F = m(a + g)[/tex]

[tex]F= mg\\\\F = 5 \times 9.8\\\\F = 49 \ N[/tex]

The acceleration of the bucket when lifted on the moon with the calculated force is;

[tex]F = m(a + g)\\\\a+g = \frac{F}{m} \\\\a = \frac{F}{m} - g\\\\a = \frac{49}{5} - 1.6\\\\a = 8.2 \ m/s^2[/tex]

Answer:

58.24 Km/h.

Explanation:

From the question given above, the following data were obtained:

Distance (d) = 495 Km

Time (t) = 8 h 30 mins

Speed (S) =?

Next, we shall express 8 hours 30 mins to hours.

We'll begin by convert 30 mins to hour.

60 mins = 1 h

Therefore,

30 mins = 30 mins × 1 h/ 60 mins

30 mins = 0.5 hour.

Thus,

8 h 30 min = 8 + 0.5 = 8.5 hours

Speed is define as the distance travelled per unit time. Mathematically, it is expressed as:

Speed = Distance /time

With the above formula, we can obtain the speed as shown below:

Distance (d) = 495 Km

Time (t) = 8.5 hour

Speed (S) =?

Speed = Distance /time

Speed = 495 Km / 8.5 hour

Speed = 58.24 Km/h

Thus, the speed is 58.24 Km/h.

Explanation:

Answer:

Answer in Explanation

Explanation:

Whenever we talk about the gravitational potential energy, it means the energy stored in a body due to its position in the gravitational field. Now, we know that in the gravitational field the work is only done when the body moves vertically. If the body moves horizontally on the same surface in the Earth's Gravitational Field, then the work done on the body is considered to be zero. Hence, the work done or the energy stored in the object while in the gravitational field is only possible if it moves vertically. This vertical distance is referred to as height. This is the main reason why we require height in the P.E formula and calculations.

The derivation of this formula is as follows:

Work = Force * Displacement

For gravitational potential energy:

Work = P.E

Force = Weight = mg

Displacement = Vertical Displacement = Height = h

Therefore,

P.E = mgh

Answer:

The height in which the book is dropped from is 1.28 m.

Explanation:

Mass of the book, m = 1.5 kg

initial velocity of the book, u = 0

final velocity of the bok, v = 5 m/s

The height in which the book is dropped from is given by;

v² = u² + 2gh

v² = 0 + 2gh

v² = 2gh

h = v² / 2g

h = (5)² / (2 x 9.8)

h = 1.28 m

Therefore, the height in which the book is dropped from is 1.28 m.

Workdone by the rope is expressed using the formula;

W = Fd sin(theta)

F is the tension in the rope = 180

d is the displacement = 300m

theta is the angle of inclination = 15°

Substitute the given parameters into the formula;

W = 180(300)sin15
