The Avengers are having a strength competition. The Hulk is tossing 1.20 x 104 kg busses so they slide on their roofs across a grassy field. The coefficient of friction between the busses and the grass is 0.185. The contestants have to use their strength to stop the bus...shortest stopping distance wins. Hawkeye steps up first. Hulk throws the bus with a velocity of 8.50 m/s[W]. Hawkeye jumps in and applies a stopping force of 4.00x103 N. Black Widow is next. Hulk throws the bus with a velocity of 8.25 m/s[W]. Black Widow remembers her physics class and instead of jumping in front of the bus, she drops a 6.00 x 103 kg steel beam onto it to increase the mass and therefore the friction force. Which bus stops in the shortest distance? Be sure to show all your work, use GRASP, and good problem solving form...and, don’t forget to include good F.B.D.s. This is one question please include as many steps as you can thank you!

1.supposed that the body with 2 kg has an initial velocity of 10m/s and is then pulled 4 meters by a force of magnitude 25N in the direction of the initial velocity, what is its final velocity?
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!

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?
