A crate of mass m is initially at rest at the highest point of an inclined plane, which has a height of 4.7 m and has an angle of θ = 28° with respect to the horizontal. After it has been released, it is observed to be traveling at v = 0.85 m/s a distance d after the end of the inclined plane as shown. The coefficient of kinetic friction between the crate and the plane is μp = 0.1, and the coefficient of friction on the horizontal surface is μr = 0.2. Find the distance d, in meters.

A crate of mass m is initially at rest at the highest point of an inclined plane which has a height of 5.28 m and makes an angle of A = 17.2° with respect to the horizontal. After it has been released, it is found to be traveling at v = 0.29 m/s a distance dafter the end of the inclined plane, as shown.

A daredevil wishes to bungee-jump from a hot-air balloon 64.5 m above a carnival midway. He will use a piece of uniform elastic cord tied to a harness around his body to stop his fall at a point 12.0 m above the ground. Model his body as a particle and the cord as having negligible mass and a tension force described by Hooke's force law. In a preliminary test, hanging at rest from a 5.00-m length of the cord, the jumper finds that his body weight stretches it by 1.65 m. He will drop from rest at the point where the top end of a longer section of the cord is attached to the stationary balloon. (a) What length of cord should he use? m(b) What maximum acceleration will he experience? m/s2

A 86.0 kg diver steps off a 10.0 m high diving board and drops, from rest, straight down into the water. If he comes to rest 7.20 m beneath the surface of the water, determine the average resistive force exerted by the water.
One end of a 34-m unstretchable rope is tied to a tree; the other end is tied to a car stuck in the mud. The motorist pulls sideways on the midpoint of the rope, displacing it a distance of 2 m (assume the car slides forward slightly in response to this, but then become stuck again). If he exerts a force of 99 N under these conditions, determine the force exerted on the car. F=F= Incorrect N
