Question

A box is pushed through 4 m across a floor offering 100 N resistance . Work done by applied force

Answer 1

Force applied,F = -100N

Displacement,s = 4m

Work done , W = Force*Displacement

= -100N*4m

=- 400Nm

= -400J

Hence, work done is 400 joules in opposite direction.

Answer 2

Answer: 500
