Answer:
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.
