Block a rests on top of block b as shown in (figure 1). The table is frictionless but there is friction (a horizontal force) between blocks a and b. Block b has mass 6. 00 kg and block a has mass 2. 00 kg. If the horizontal pull applied to block b equals 12. 0 n, then block b has an acceleration of 1. 80 m/s2.

Answers

Answer 1

The acceleration of block A is 0.6 m/s².

Net force on the blocks

The net force on the blocks is determined by applying Newton's second law of motion.

∑F = ma

Acceleration of bock A

The acceleration of block A is calculated by applying Newton's second law of motion as follows;

[tex]F_a + F_b = F\\\\F_a = F-F_b\\\\m_a a_a = F- m_ba_b\\\\a_a = \frac{F- m_ba_b}{m_a}[/tex]

Where;

Mb is mass of block B = 6 kgMa is mass of block A = 2 kg[tex]a_b[/tex] is acceleration of block B = 1.8 m/s²[tex]a_a[/tex] is the acceleration of block A = ?

[tex]a_a = \frac{12\ - \ 6 \times 1.8}{2} \\\\a_a = 0.6 \ m/s^2[/tex]

Thus, the acceleration of block A is 0.6 m/s².

Answers

The angle of elevation at which he kicks the ball is; 36.89°

Finding the angle of elevation

We are told that the ball is 12 ft away and so we will consider it to be the horizontal distance.

The post is 8 ft high and so we will consider it to be the vertical distance.

Thus, we can use trigonometric ratio to find the angle of elevation. Thus;

tan θ = 8/12

θ = tan⁻¹0.75

θ = 36.89°

In conclusion the angle of elevation at which he kicks the ball is 36.89°

A radar gun was used to record the speed of a runner during the first 5 seconds of a race (see the table). Use simpson's rule to estimate the distance the runner covered during those 5 seconds. (round your answer to three decimal places. ).

Answers

The sum of the product of the times and velocity is given by the definite

integral of the function of velocity which is given by Simpson's rule.

Response:

The distance the runner covered during the 5 seconds is approximately 44.772 m

What is the Simpson's rule, and how can it be used to estimate the distance?

The Simpson's rule is used for to approximate a definite integral

The possible table of values of the velocity and time obtained from a similar question is presented as follows;

[tex]\begin{array}{|c|c|c}t(s)&v(m/s)&\\0&0\\0.5&4.67\\1.0&7.32&\\1.5&8.84&\\2.0&9.73&\\2.5&10.24&\\3.0&10.57&\\3.5&10.63&\\4.0&10.76&\\4.5&10.87&\\5.0&10.87&\end{array}\right][/tex]

Distance = Velocity × Time

[tex]The \ distance \ is \ given \ by \ the \ integral, \ \mathbf{\displaystyle \int\limits^a_b {f(t)} \, dt}[/tex]

Where;

f(t) = v

dt = Small duration in time

According to Simpson's rule, we have;

[tex]\displaystyle \int\limits^a_b {f(x)} \, dx = \mathbf{\frac{\Delta x}{3} \left(f(x_0) + 4 \cdot f(x_1) + 2\cdot f(x_3) + ... + 2\cdot f(x_{n - 2}) + 4 \cdot f(x_{n-1}) + f(x_n) \right)}[/tex]

Δx = [tex]\mathbf{\dfrac{b - a}{n}}[/tex]

n = 10

Which gives;

[tex]\dfrac{5.0 - 0}{10} = \dfrac{1}{2} = 0.5[/tex]

[tex]d = \displaystyle \int\limits^a_b {f(t)} \, dt = \mathbf{ \frac{0.5}{3} \left(f(t_0) + 4 \cdot f(t_1) + 2\cdot f(t_3) + ... + 2\cdot f(t_{10 - 2}) + 4 \cdot f(t_{10-1}) + f(x_{10}) \right)}[/tex]

Therefore;

d = 0.5÷3×(0 + 4 × 4.67 + 2 × 7.32 + 4 × 8.84 + 2 × 9.73 + 4 × 10.24 + 2 × 10.57 + 4 × 10.63 + 2 × 10.76 + 4 × 10.87 + 10.87) ≈ 44.772

The estimate of the distance covered during the 5 seconds, d ≈ 44.772 m

Explanation:

A metal wire has a circular cross section with radius 0. 800 mm. You measure the resistivity of the wire in the following way: you connect one end of the wire to one terminal of a battery that has emf 12. 0 v and negligible internal resistance. To the other terminal of the battery you connect a point along the wire so that the length of wire between the battery terminals is d. You measure the current in the wire as a function of d. The currents are small, so the temperature change of the wire is very small.

Answers

Answer:

[tex]\rho[/tex] = V*π*r^2/(I*d)

Explanation:

Radius r = 0.800 mm, so Area = π x r^2

Voltage V = 12.0 V

Length = d

resistivity = [tex]\rho[/tex]

Current = I

Resistance R = V/I = [tex]\rho[/tex] * d/(π * r^2)

so

[tex]\rho[/tex] = V*π*r^2/(I*d)
