If a ball of mass 0.5 kg flies with a speed of 8 m/s toward a wall, how much impulse would it transfer to the wall if it bounces back with a speed of 6 m/s right after hitting the wall?

impulse = - 1 kg m/s

Explanation:

Given

mass = 0.5 kg

initial velocity = 8 m/s

final velocity=6 m/s

Find

impulse = ?

Formula

Impulse = F*t = m (final velovity) - m (Initial velocity)

Solution

impulse = 0.5kg (6 m/s) - 0.5kg (8 m/s)

= 3 kg m/s - 4 kg m/s

= - 1 kg m/s
