A horizontal force of 750 N is needed to overcome the force of static friction between a level floor and a 250-kg crate. What is the acceleration of the crate if the 750-N force is maintained after the crate begins to move and the coefficient of kinetic friction is 0.12?

The acceleration of the crate is .

Explanation:

Given that,

Force, F = 750 N

Mass of the crate, m = 250 kg

The coefficient of friction is 0.12.

We need to find the acceleration of the crate. The net force acting on the crate is given by :

f is frictional force,

So, the acceleration of the crate is . Hence, this is the required solution.

true tan speed = ang vel x radius

i had this question and the answer was 3.15 miles.
