Concept

Problem: A nurse pushes a cart by exerting a force on the handle at a downward angle 35° below the horizontal. The loaded cart has a mass of 28.0 kg, and the force of friction is 60.0 N. (a) Draw a free-body diagram for the system of interest. (b) What force must the nurse exert to move at a constant velocity?

FREE Expert Solution

Newton's second law:

ΣF=ma

(a)

The nurse pushes the cart at an angle below the horizontal.

For the cart to move at a constant velocity, the net force in the horizontal direction will be zero.
