1) A skier starts from rest at the top of a hill. The skier coasts down the hill and up a second hill. The crest of the second hill is circular, with a radius of 36 m. Neglect friction and air resistance. What must be the height of the hill so that the skier just loses contact with the snow at the crest of the second hill?

A car travelling at 25.0 m/s runs out of gas while travelling up a 33.0 degree slope. How far up the hill would it coast before starting to roll back down.
whose first two components are the polar coordinates of the horizontal displacement between the planes, and whose third coordinate is the vertical displacement between the planes. Consider east to be the positive x axis and north to be the positiv..
A ski gondola is connected to the top of a hill by a steel cable of length 680 m and diameter 1.5cm. As gondola comes to the end of its run, it bumps into the terminal and sends a wave pulse along cable. It is observed that it took 14 s for the p..
