Question

A shopper pushes a grocery cart with a force F of 50 N downward and to the right, as shown in the figure below. The anglethe handle makes with the horizontal is 37°, and the cart is moved 14 m. Find the work W done, in joules (1).Ed

Answer 1

For this case we can create the following plot:

We want to find the work so we can use this formula:

`W=Fd\cos \theta`

Replacing we got:

`W=50\cdot14m\cdot\cos 37=559.04J`
