Students set up an inclined plane surface, as shown below. It is angled at 10° to the horizontal. They place a frictionless trolley of mass 0.50 kg at the top of the incline, so that the distance from the front of the trolley to the stopper at the bottom is 3.5 m

Context: m The object of mass m = 3 kg is at the bottom of the incline, which is at the angle e = 55° with respect to horizontal. The object has initial speed of vo = 5 m/s and begins slide up the incline. There is a friction between the object and the incline. The coefficient of kinetic friction is uk = 0.25. The object moves up the incline and eventually stops under the influence of friction and its own weight. Find: (a) how high up the incline (in m, relative to its original position) the object slides before stopping (careful here - your answer is the height, i.e. the vertical distance between object's final position and the ground); (b) work in J) done by the kinetic friction when the object moves up the incline (careful with the sign); (c) work in J) done by the normal force when the object moves up the incline; (d) work in J) done by the gravity when the object moves up the incline (careful with the sign); (e) when the object reaches the highest point on the incline it begins to slide back down, find object's speed (in m/s) at the bottom of the incline. Answer question

A small package is deposited by the conveyor belt onto the 30o ramp at A with a velocity of0.8m/s. Calculate the distance s on the level surface BC at which the package comes to rest.The coefficient of kinetic friction for the package and supporting surface from A to C is 0.3.
