Question

025 (part 1 of 4) 10.0 points A man pushes a 24 kg box across a frictionless floor. The box is initially at rest. He initially pushes on the box gently, but gradually in- creases his force so that the force he exerts on the box varies in time as F (7.7 N/s) t. Af- ter 4 s, he stops pushing the box. The force is always exerted in the same direction. What is the velocity of the box after 4 s? Answer in units of m/s 026 (part 2 of 4) 10.0 points How far has the man pushed the box in 4 s?
