Question

You push a 35.5‑kg wooden box
across a wooden floor at a constant speed of 1.5 m/s. The coefficient of
kinetic friction is 0.15. How large is the force that you exert on the box?

Answer 1

Explanation:

Friction = 0.15× mg

= 0.15× 35.5 × 10

= 532.5 N

Force = Friction { because body is moving with constant speed}

Force = 532.5 Newton.
