A man pushes on a 75.0 kg box such that his force of 225 N is exerted at an angle of 27.0o to the horizontal as shown.
(a) If the floor exerts a frictional force of 44.0 N on the box, what is the net force acting on the box?
(b)If the box is initially at rest, how far will it have been pushed in 5.00 s assuming those forces continued?

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...
