In a physics lab, a cube slides down a friction-less incline as shown the figure below and elastically strikes another cube at the bottom that is only one-half its mass. If the incline is h = 28 cm high and the table is H = 85.1 cm off the floor, where does the larger cube land, in cm, horizontally away from the edge of table? [Hint: Both leave the incline moving horizontally.]

A skier of mass 75kg starts from rest at the top of a friction less incline that is 20.0 m in height. As soon as she touches the bottom of the incline, she encounters a horizontal surface that is 1000 m long and the skier eventually comes to rest. The coefficient of kinetic friction between skier and snow is 0.205. Find the distance the skier covers before coming to rest. Show all work.

8. A cart slides down an inclined plane with the angle of the incline θ starting from rest. At the moment the cart begins to move, a ball is launched from the cart perpendicularly to the incline. (a) Choosing an x-y-coordinate system with the x-axis along the incline and the origin at the initial location of the cart, derive the equation of the trajectory that the ball assumes from the perspective of this coordinate system. (b) Determine where the maximum...

A 150g ball slides down a perfectly smooth incline starting at a height of 2.44m, at rest. At the bottom of the incline is strikes and sticks to a 280g block. The block/ball combo are then free to move along a frictionless rollercoaster track. The first hill is only 23 cm high. Can it make it over this first hill? Defend your response with detailed analysis. If the combo CAN make it over the hill, how fast is it moving...
