iren [92.7K]

The magnitude of the average force exerted on the ball by the wall is 225.469 N.

<h3>What is impulse?</h3>

The change in momentum is equal to the product of impact force applied while colliding and time for that impact.

Impulse F. t = m (Vf -Vi)

where, Vf is the final velocity and Vi is the initial velocity.

Given is a 3.42 kg steel ball strikes a massive wall at 14.3 m/s at an angle of α = 61.5° with respect to the plane of the wall. It bounces off with the same speed and angle. The ball is in contact with the wall for 0.207 s

Substitute the values into the expression, we get

Impulse = 2 x mvcosθ

Impulse= 2 x 3.42 x 14.3 x cos 61.5°

Impulse = 46.672 kg.m/s

The impact force can be written as

F.t = I

Put the given values, we have

F = 46.672 /  0.207

F = 225.469 N

Thus, the magnitude of force exerted by the wall is 225.469 N

6. f = 128.62 s^{-1} , T= 0.0077775 s

7. f  = 2.2 * 10^{4} s^{-1}, T = 4.545 * 10^{-5} s

8. 32.64 s^{-1}

9. 3.29 * 10^{14} s^{-1}

Explanation:

Step 1:

6.

For light and sound v = fλ

where v represents the velocity

f represents the frequency

λ represents the wavelength

λ = 2.69 m

v = 346 m/s

f = v/λ = 346/2.69 = 128.62 s^{-1}

Time period is the reciprocal of frequency

T = 1/128.62 = 0.0077775 s

Step 2:

7.

λ = 110 cm = 1.1 m

v = 2.42*10^{4} m/s

f = 2.42*10^{4}/1.1 = 2.2 * 10^{4} s^{-1}

T = 1/(2.2*10^{4}) = 4.545 * 10^{-5} s

Step 3:

8.

λ = 10.6 m

v = 346 m/s

f = v/λ = 346/10.6 = 32.64 s^{-1}

Step 4:

9.

λ = 5.89 * 10^{-7} m

v = 1.94 * 10^{8} m/s

f = v/λ = 3.29 * 10^{14} s^{-1}
