The 0.07-kg particle has a speed v = 8.6 m/s as it passes the position shown. The coefficient of kinetic friction between the particle and the vertical-plane track is μk = 0.24. Determine the magnitude of the total force exerted by the track on the particle. What is the change in speed v˙ (positive if speeds up, negative if slows down) of the particle? Answers: F = N v˙ = m/s2

A block with a mass m = 2.34 kg is placed at the top of a hinged incline plane with a length L = 1.47 m. The angle the plane makes with the horizontal is slowly increased. The block starts to slide when θ = 24.8∘. The coefficient of kinetic friction between the block and the plane is μk = 0.338. Part 1) What is the coefficient of static friction between the block and the plane? μs = Part 2) What is the net force on the block as it slides down the inclined plane (when it is inclined at θ = 24.8∘)? Fnet = N down the plane Part 3) What is the speed of the block at the bottom of the inclined plane (it starts from rest at the top of the plane)? v = m/s

A hanging weight, with a mass of m1 = 0.360 kg, is attached by a string to a block with mass m2 = 0.850 kg as shown in the figure below. The string goes over a pulley with a mass of M = 0.350 kg. The pulley can be modeled as a hollow cylinder with an inner radius of R1 = 0.0200 m, and an outer radius of R2 = 0.0300 m; the mass of the spokes is negligible. As the weight falls, the block slides on the table, and the coefficient of kinetic friction between the block and the table is μk = 0.250. At the instant shown, the block is moving with a velocity of vi = 0.820 m/s toward the pulley. Assume that the pulley is free to spin without friction, that the string does not stretch and does not slip on the pulley, and that the mass of the string is negligible. (a) Using energy methods, find the speed of the block (in m/s ) after it has moved a distance of 0.700 m away from the initial position shown. m/s (b) What is the angular speed of the pulley (in rad/s) after the block has moved this distance? rad/s

A small block of mass m = 3.25 kg is fired with an initial speed v0 = 4 m/s along a horizontal section of frictionless track, as shown in the top portion of the figure. The block then moves along the frictionless semicircular vertical track of radius R = 0.5 m. Part 1 Determine the force exerted by the track on the block at point A. F = Part 2 The bottom of the track consists of a horizontal section (L = 14 m) with friction. Determine the coefficient of kinetic friction between the block and the bottom portion of the track if the block just makes it to point B before coming to rest. μk = number (rtol = 0.05, atol = 1 e−08)
