A 121 kg crate is sitting at the top of a ramp, which is inclined at an angle of 18 degrees with respect to the horizontal. The crate is a height 0.51 m from the ground, measured vertically from the ground to the crate. Someone gives the crate a quick shove to get it moving, after which it slides down the ramp without any further assistance. The coefficient of kinetic friction between the crate and the ramp is Hs = 0.23. How much time (in seconds) does it take for the crate to get to the base of the ramp?

A person slides a bottle with mass 0.20 kg along a level table. It leaves his hand at 2.8 m/s and comes to a halt after going 1.0 m. Find the coefficient of kinetic friction between the bottle and the table.
A block is placed on a wooden plank, which is initially horizontal. One end of the plank is slowly raised to make it more and more inclined, and for a while the block stays in place on the plank and doesn't slide due to static friction. Finally, when the plank reaches an incline of 56.3oabove horizontal, the block begins to slide. What is the coefficient of static friction between the block and the plank?

You are helping a friend move. Consider two boxes which have masses in factors ofm; one of mass 6m and the other of mass 7m. The coefficient of static friction betweenthe two boxes is very large. The coefficient of static friction between the boxes and thefloor is 0.7 and the coefficient of kinetic friction is 0.1. You place the large box on top ofthe small box and slide them down a 1m high ramp out of the truck. The ramp isfrictionless because it is covered with wheels. The box slides down this ramp smoothlyonto the horizontal grass with coefficient of kinetic friction is 0.142857142857143. Howfar (in meters) will the boxes slide before they stop?
A parachutist whose mass is 65 kg drops from a helicopter hovering 2500 m above the ground and falls toward the ground under the influence of gravity. Assume that the force due to air resistance is proportional to the velocity of the parachutist, with the proportionality constant b, = 30 N-sec/m when the chute is closed and b, = 100 N-sec/m when the chute is open. If the chute does not open until the velocity of the parachutist reaches 15 m/sec, after how many seconds will the parachutist reach the ground? Assume that the acceleration due to gravity is 9.81 m/ sec2. .. The parachutist will reach the ground after seconds. (Round to two decimal places as needed.)
