You throw a ball with a mass of 0.50 kg against a brick wall. It hits the wall moving horizontally to the left at 20 m/s and reb
Orlov [11]

Answer:

The value of impulse of the net force on the ball during its collision with wall is  I = 15\ kg \frac{m}{s}

The value of average horizontal force that the wall exerts on the ball during the impact is F = 15000 N

Explanation:

Mass of the ball = 0.5 kg

Horizontal velocity V_{x} = 20 \frac{m}{s}

Velocity after collision V_{-x} = - 10 \frac{m}{s}

(A). Impulse of the net force on the ball during its collision with wall is

I =  m (V_{x} - V_{-x})

I = 0.5 × (20 + 10)

I = 15\ kg \frac{m}{s}

This is the value of impulse of the net force on the ball during its collision with wall.

(B). The magnitude of average horizontal force

F = \frac{I}{T}

Where F = Force

I = impulse & t = time interval = 0.001 sec

F = \frac{15}{0.001}

F = 15000 N

This is the value of average horizontal force that the wall exerts on the ball during the impact.
