The 114-kg crate of the figure below is being moved by a rope that passes over a smooth pulley. The coefficient of friction between the crate and the floor is 0.4. If h = 4 m, determine the force P necessary to produce impending motion in N. 2 m 5 m h
A carnival ride has people stand inside a vertical cylinder with their backs to the wall. The cylinder starts spinning and the riders find that they are “stuck” to the wall and don’t slide down, even if the floor is removed. The ride has a radius of r. The person has a mass of m and is moving with a constant speed of v. The coefficient of static friction between the person and the wall is μs , and kinetic friction μk. The person is only touching the wall, not touching the floor. What is the magnitude of the acceleration of the person? In what direction does it point? The speed is constant. Why is the acceleration not zero? Briefly explain. No equations!

3. Two blocks, mı = 9 kg and mɔ = 15 kg, are connected by a light string that passes over a frictionless pulley as shown in the figure. The first block lies on a horizontal surface and is connected to a spring with 45 N/m force constant. The system is released from rest when the spring is at equilibrium (unstretched). If the kinetic friction between mị and the surface is 0.20, calculate: (a) the distance h which the hanging block falls before coming to rest. (b) the work done by the spring on mị (c) the work done by the string on m || k

Two blocks of mass m = 2.00 kg are connected by a vertical string of negligible mass and unknown tension Tm are hanging vertically. The higher one of these two masses is directly attached to another string of negligible mass and unknown tension T that goes over a frictionless pulley of negligible mass and is connected to a third block of mass M = 6.00 kg. The heavier block is free to slide on an incline (of angle 0 = 30.0° w.r.t. the horizontal) with coefficients of kinetic friction of µA = 0.120 and static friction µ,=0.150 between the block and the incline. The system is released from rest. !! M a) Please perform a test to determine which way the system would like to move in the absence of any friction. b) Please perform a test to determine whether the system will be able to overcome the maximum of static friction and be able to move, or remain at rest instead. c) Determine the magnitude of the normal force N exerted on the third block by the incline. d) Determine BOTH the magnitude…
