Question

Pam has a mass of 35.5 kg and she is at rest on smooth, level, frictionless ice. Pam straps on a rocket pack. The rocket supplies a constant force for 29.2 m and Pam acquires a speed of 64.1 m/s.
What is the magnitude of the force?

Henry · Answer

V^2 = Vo^2 + 2a*d V = 64.1 m/s Vo = 0 d = 29.2 m. Solve for a. F = M*a M = 35.5 kg Solve for F.
