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?

A boy pulls his younger sister on a toboggan by a rope that makes an angle of 37.0° with the horizontal, as shown. The boy maintains a tension of 25.0 N in the rope and walks, on level ground, at a constant speed of 1.10 m/s. The combined mass of the girl and the toboggan is 30.0 kg. Determine a. the normal force exerted on the toboggan by the ground. the coefficient of kinetic friction between the...
