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?

Respuesta :

Answer:

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
