How large must the force of friction be in order to keep a 75kg person in...
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...

[BONUS20pts] A 1,500kg sports car negotiates a curve with 25m radius.The static friction coefficient to keep the tires on the road is u = 0.75. [a] What is the maximum possible speed that the car can have in the curve before drifting off? [b] How is it different for a 20 ton truck? [c] What is the value of the smallest curve radius without drifting for a car twice as fast? CVP
[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?...
2) In the drawing above, object A has 10 times the mass of object B. Each object produces gravitational field that exerts a force on the person. The distance between the centers of objects A and B is d. The person is standing a distance of 3/4 d from object A , what is the net gravitational force exerted on the person ( magnitude and direction). 3) Two banked curves have the same radius. Curve A is banked at an...
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...
