Pam, wearing a rocket pack, stands on frictionless ice. She has a mass of 44 kg. The rocket supplies a constant force for 22.0 m, and Pam acquires a speed of 62.5 m/s. Assume that air resistance is negligible.

Question

(a) What is the magnitude of the force?

Answer 1

Force x distance = change in kinetic energy
Force = (1/2) M V^2/(22 meters)
= (1/2)*44*(62.5)^2/22 = ___ Newtons
