Question

A person is pulling a freight cart with a force of 59 pounds. How much work is done in moving the cart 80 feet if the cart’s handle makes an angle of 30° with the ground?

Answer 1

Answer:

W = 29.5 J

Step-by-step explanation:

It is given that,

Force acting on a freight cart is 59 pounds

We need to find the work done in moving the cart 80 feet if the cart’s handle makes an angle of 30° with the ground. The product of force and displacement is called work done. It can be written by :

$W=F_x\times d$

$F_x$ is the horizontal component of force

$W=59\times \cos30\times 80\\W= -29.5\ J$

So, the magnitude of work done by the cart is 29.5 J.
