A10- kilogram block is pushed across a horizontal surface with a horizontal force of 20 n against a friction force of 10 n. the acceleration of the block

Explanation:

Mass of block=10 kg

Applied horizontal force =F=20 N

Friction force=f=10 N

We have to find the acceleration of block.

Net force=Applied horizontal force-friction force

Where F= Horizontal force

f=Friction force

m=Mass of object

a=Acceleration of object

Hence, the acceleration of the block=
