A cat (mass of 3.63 kg) is on a sled (mass of 22.7 kg) which rests on an icy surface... so no friction. In front of this sled, there is another identical sled. The cat jumps from the first sled to the second AND immediately back to the first. Both jumps are made at a relative speed of 3.7 m/sec between the cat and the sled it is on. Calculate the final speeds of the two sleds!
Two people are in bumper cars on opposite sides of a halfpipe, as shownbelow. Both are released from rest, and both bumper cars have a mass of 500 kg. The personin the red car, staring on the left side of the halfpipe, has a mass of 70 kg and starts 2 m abovethe bottom of the ramp. The person in the blue car, staring on the right side of the halfpipe,has a mass of 80 kg and starts 2.5 m above the bottom of the ramp. Upon colliding, the bumpercars bounce off one another. After the collision, the blue car returns to a height of 1.75 m abovethe bottom of the ramp. What is the height the red car reaches?
Sam, whose mass is 74.0 kg, takes off across level snow on his jet-powered skis. The skis have a thrust of 220.0 N and a coefficient of kinetic friction wtih the snow of 0.07. Unfortunately, the skis run out of fuel after only 11.5 seconds. What Sam's top speed (in m/s) assuming that the acceleration due to gravity is 9.80 m/s2? How far (in m) has Sam traveled when he finally coasts to a stop?
