Explanation:
I tried it and got it right.
Answer:
Net force = 25N and in the right direction
Explanation:
mass of box, m = 50kg
Force of block = 150N
Friction force = 125N

150 - 125 = 25N
the force applied to the block is greater than the friction force. there the force applied will overcome the friction force and move in the right direction of the force applied
