1) A uniform 14 kg cylinder turns on a horizontal axis with a
significant amount of friction. The cylinder has a radius of 0.030
m and a thickness of 0.080 m. It is initially at rest. Then a force
of 70 N is applied at a 37 angle for 2.0 s, as indicated in the
figure, and the cylinder accelerates. After a time of 2.0 s the
force is reduced to 24 N, and then the cylinder continues to spin...

[33] A Merry-Go-Round (thin solid disk of mass M-2000 kg and rotational inertia ofla k-1 MR2)is rotating freely, without friction, at 46 rpm. Three people step on the very edge of the Merry-Go-Round (Gi.e. at a distance R from the center), each with a mass of m 80.0 kg (treat them as point particles). Determine the new angular speed of the Merry-Go-Round in rad/s. b. a. How many revolutions does it turn in 2.0 min, after the people get on?...

4) There is a large horizontal disc with a radius of 5 meters. Gerald Chen is sitting on the edge of this disc. How fast (in rad/s) can the disc spin so that Gerald Chen does not fall off? The coefficient of friction between Fryderyk and the disc is 0.5 Imagine we have a horizontal spring with that is 10 meters long at equilibrium. This spring is meant to stop cars. If a car with a mass of 1500kg has...

a) A man jumps off the roof of an office building onto a trampoline 30 m below. His speed is 5 m/s when he umps from the roof and his mass (with all of her gear) is 60 kg. How high will he go when he bounces back up from the trampoline? You can assume his speed at the top of his bounce is zero. b) Describe the changes in mechanical energy that take place during his jump. c) A...
