A 63 kg person starts traveling from rest down a waterslide 7.0 m above the ground. At the bottom of the waterslide, it then curves upwards by 1.0 m above the ground such that the person is consequently launched into the air. Ignoring friction, how fast is the person moving upon leaving the waterslide? Fynress MOur

A small object begins a free fall from a height of 29.0 m. After 1.10 s, a second small object is launched vertically upward from the ground with an initial velocity if 37.0 m/s.   At what height h above the ground will the two objects first meet? Asked to use the equation y=y0+v0yt--1/2gt^2 and assume gravity as I believe 9.8 m/s^2

8. A skier starts from rest at the top of a 20° incline and skis in a straight line to the bottom of the slope, a distance d (measured along the slope) of 400 m. If the coefficient of kinetic friction between the skis and the snow is 0.2, calculate the skier's speed at the bottom of the run.

Mike uses a block sliding down an inclined plane to estimate the coefficient of kinetic friction, uk, between the block and the plane. He adjusts the inclined plane to an angle 45° above the horizontal, and allows the block to slide down the plane from rest. He uses motion detector with a computer interface to get the velocity of the block when it reaches the bottom of the plane. The distance the block slides down the inclined plane is 1.15 m. The speed of the block at this point is 2.2 m/s. Using conservation of energy, estimate uz.
