A1.000 kg boulder rolls 75 m down a mountain doing 735,000 j of work.
what force was acting on the boulder?

9800 N

Explanation:

The work done by the boulder is equal to the product between the force acting on it and the distance covered by the boulder:

where

F is the magnitude of the force

d is the distance covered by the boulder

Here we know

W = 735,000 J is the work done

d = 75 m

Solving the equation for F,

This force is actually equal to the force of gravity acting on the boulder, which is given by:

where

m = 1000 kg is the mass of the boulder

is the acceleration of gravity

Substituting,

it about 600 mph from what i calculated

the answer is a)
