Anurse pushes a cart by exerting a force on the handle at a downward angle of 36 degrees below the horizontal. the loaded cart has a mass of 28kg, and the force of friction is 65 n. what is the magnitude of force the nurse must exert to move at a constant velocity in newtons?

Since it was stated that it must move at constant velocity, so the only force it must overpower is the frictional force.

So the equation is:

F cos θ = Ff

F cos 36 = 65 N

F = 80.34 N

So the nurse must exert 80.34 N of force
