Hello all. Great site here. I have been working on this problem for a while now and I cannot figure out the magnitude of the force.(adsbygoogle = window.adsbygoogle || []).push({});

Pam, wearing a rocket pack, stands on frictionless ice. She has a mass of 45 kg. The rocket supplies a constant force for 22.0 m, and Pam acquires a speed of 62.5 m/s. Unless otherwise directed, assume that air resistance is negligible. What is the magnitude of the force? What is Pam's final Kinetic Energy?

How do you figure out the force when time is not a given? I have tried 441 N but it is wrong. (This is internet homework and I have used up 2 submissions. I have 8 submissions left.)
