A cannonball is launched horizontally from the top of a 166 m
cliff with an original speed of 35.9 m/s.

Determine the horizontal displacement (in m) of the cannonball.

Work is characterized as a force that causes an object to move or be displaced.  The work done would be 455040.

Work is the scalar product of the force acting on an object and the displacement that force causes when the force is constant.

Despite the fact that work lacks a direction due to the scalar product (or dot product) aspect of vector mathematics, force and displacement are both vector quantities.

"W" stands for work, "F" is the force, and "d" represents displacement (or the distance the object travels).

Therefore, Work is characterized as a force that causes an object to move or be displaced.  The work done would be 455040.

The potential impacts of global climate change on thermohaline circulation in the oceans is increasing the rate of circulation. That is option D.

The thermohaline circulation is defined as the process by which deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline).

When there is global climate change increased temperature of water masses would cause these currents to flow faster given the higher kinetic energy of the water molecules.

The mass added to the object to change the period to 2.05 s is 0.42 kg

What is the time period of an oscillation?

The time taken for an oscillating particle to complete one cycle of oscillation is known as the Period of oscillating particle.

Given :

A 0.480-kg mass suspended from a spring oscillates with a period of 1.50 s.

The formula of the time period is given by:

 [tex]T=2\pi \sqrt{m/K}[/tex] ------(1)

where m is the mass and K is the spring constant.

The new time period is given by:

[tex]T'=2\pi \sqrt{m^{'} /K[/tex]-----(2)

where m' is the total mass after the addition and K is the spring constant.

Dividing equation (1) by equation (2).

[tex]T/T'=\sqrt{m/m'}[/tex]

Now, substitute the known terms in the above expression.

[tex]\frac{1.50}{2.05} =\sqrt{0.480/m'}[/tex]

[tex]m'=\frac{0.480}{0.5329}[/tex]

[tex]m'=0.9[/tex] kg

Now, the mass added to the object to change the period to 2.05 s is given by:

What is magnitude ?

According to the physics definition, magnitude is just "distance or quantity." It demonstrates how an object moves as it is moving, including whether the movement is absolute, relative, or of a particular size. It serves as a means of describing the size or scope of something. Physicists use the word "magnitude" to indicate size or distance.

What is gravitational force ?

The force of attraction between any two bodies is directly proportional to the product of their masses and is inversely proportional to the square of their distance, according to Newton's universal law of gravitation.

The piston's position, velocity, and acceleration at t = 1.15 s are :

Position: 3.45 m

Velocity: 3 m/s

Acceleration: 0 m/s^2

To calculate the piston's position, velocity, and acceleration at t = 1.15 s, we need to know the angular position, velocity, and acceleration of the wheel.

The angular position of the wheel at t = 1.15 s is given by

θ = ωt + [tex]A_{0}[/tex]

where ω is the angular frequency, t is the time, and [tex]A_{0}[/tex] is the initial angular position.

Since the angular frequency is given as 12 rad/s and the initial angular position is 0, the angular position of the wheel at t = 1.15 s is

θ = 12 x 1.15 = 13.8 radians

The piston's position is given by

r = Rθ

where R is the radius of the wheel.

Substituting the value of R and θ,

r = 0.25 x 13.8 = 3.45 m

The velocity of the piston is given by

v = r' = Rθ' = Rω

Substituting the values

v = Rω = 0.25 x 12 = 3 m/s

Acceleration of the piston is given by

a = v' = Rθ'' = Rω' = R(ω^2)θ

As the angular frequency is constant, the angular acceleration is 0 so the linear acceleration is also 0.

Note: Linear acceleration is not equal to the derivative of linear velocity, it is equal to the derivative of velocity with respect to time, which is zero in this case.

To lift loads up to 120 tons, tower cranes are utilized at large building sites. In a tower crane, a fixed and a moveable counterweight are held by two arms that extend from the center of the structure. For the purpose of balancing the load, the operator moves the mobile counterweight.

For the purpose of providing offset forces in the flight controls, counter weights are used. With less pressure needed to move the controls, this gives them better "feel" and "feedback" forces.

After the collision,

Ball A has a velocity = -1.5 m/s.

Let   Ball B has a velocity = v m/s.

Applying   law of conservation of momentum,

The required average velocity vector for the trip is calculated to be 100 i + 200 j and its magnitude is 223.6 km/h.

The displacement due east is taken as 150 i.

The displacement due south is taken as 300 j.

The net displacement is given as, 150 i + 300 j.

Magnitude of net displacement = √(150² + 300²) = √112500 = 335.41 km

We get the average velocity by dividing the displacement vector by total time.

v avg = (150 i + 300 j)/1.5 = 100 i + 200 j

Magnitude of net velocity = √(100² + 200²) = √(10000 + 40000) = 223.6 km/h
