A nurse pushes a cart by exerting a force on the handle at a downward angle 38° below the horizontal. The loaded cart has a mass of 28 kg, and the force of friction is 61 N.

Randomized Variables

f = 61 N

a = 38 °

What is the magnitude of the force the nurse must exert to move at a constant velocity in Newtons?
