A truck has a momentum of 5.8x10^4 Ns [S]. An average force of 2.2x10^3 N [S] increases the truck's momentum for the next 8.8s. What is the impulse and final speed of the truck?

Answer 1

impulse = change of momentum = force * time

impulse = 2.2*10^3 * 8.8 = 19.36*10^3 Ns

final momentum = 5.8*10^4 + 1.94*10^4 = 7.74 Ns

need to know mass in kg
v = 7.74/mass
