Aball traveling with an initial momentum of 5.1 kgm/s bounces off a wall and comes back in the opposite direction with a momentum of -4.3kgm/s.
what is the change of momentum of the ball?
what impulse is required to produce this change?

-9.4 kg m/s

Explanation:

Change in momentum = final momentum − initial momentum

Δp = p − p₀

Δp = -4.3 kg m/s − 5.1 kg m/s

Δp = -9.4 kg m/s

Impulse = change in momentum

J = Δp

J = -9.4 kg m/s

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
