Calculate the work done by the pushing force

Reference no: EM13533402

A person pushes a 12.3-kg shopping cart at a constant velocity for a distance of 16.5 m on a flat horizontal surface. She pushes in a direction 24.2 ° below the horizontal. A 51.0-N frictional force opposes the motion of the cart.

(a) What is the magnitude of the force that the shopper exerts?

Determine the work done by (b) the pushing force,

(d) the gravitational force.
