Question

A 5kg cart moving to the right with a velocity of 16 m/s collides with a concrete wall and

rebounds with a velocity of 22 m/s. Is the change in momentum of the cart​

Answer 1

Step-by-step explanation:

mass, m = 5kg

initial velocity, u = 16m/s

final velocuty, v = -22m/s

change in momentum, ∆p = ?

∆p = m (v-u)

5(-22-16)

5(38)

∆p = 190kgm/s
