Answer:

Step-by-step explanation:
Given: A
steel crate is being pushed along a cement floor. The force of friction is

to the left and the applied force is

to the right.
To Find: What is the acceleration of the crate.
Solution:
Mass of steel crate

Force of friction on steel crate

Force applied on steel crate

Now,
As force of friction is in opposite direction of force applied
Net force applied on steel crate






putting values

Hence acceleration of crate is
