Ariel skiing involves speeding down a steep ramp that curves sharply upward at the end to launch the skiers into the air. Once airborne skiers twist and turns into Contacts combinations to score points in the competition. Consider an aerial launch ramp that has a final launch slope of 52.9° above the horizontal. Given this angle a skier flies to 17.1 m above the end of the ramp. From this information determine the skiers launch speed

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

Acrow drops a 0.11kg clam onto a rocky beach from a height of 9.8m. what is the kinetic energy of the clam when it is 5.0m above the ground? what is its speed at that point?
