Please show work

Question 3

You throw a rock from the edge of a 54.0 m high cliff. The initial velocity of the rock is 25.6 m/s at an angle of 24.5° up from the horizontal. How long is the rock in the air? How far from the base of the cliff does it land?

Question 4

A sled is traveling at 15.0 m/s. It slides to rest under the influence of friction in 2.54 s. What is the coefficient of kinetic friction required to do this?

Question 5

An object is at equilibrium under the influence of three forces. One for is applied at 25° North of West. The second is applied at 35° North of East. What is the magnitude and direction of the third force?

You throw a small rock straight up from the edge of a highway bridge that crosses a river. The rock passes you on its way down, 6.00 s after it was thrown. After the rock hits the surface of the water it sinks into the water through a depth of 1.0 meter and reached a speed of .5 m/s. What is the rate of slowing down for the rock in the water during this 1 meter travel, assuming it slows...
