Part 2 After reaching the top of the incline, the box of mass 1 kg is released, and allowed to slide back down the hill of incline angle 0 20 At the halfway point, the surface of the incline becomes rough, and friction becomes important The coefficients of friction between the box and hill are μ-: 0.7 and μ.-0.5. 0 20 D. Draw a free body diagram for the object as it moves down the incline as it encounters the...
A 5.0 kg chair sits on a ramp which is at an angle of 10^0 with respect to the horizontal. A boy wants to push the chair up the ramp. The coefficient friction between the chair and the floor is (0.3, 0.2) Draw a free-body diagram. Does the boy need to push on the chair to keep it from sliding down the incline? (Be sure to show your work.) If the chair is at rest, then what is the maximum...
2.00 m 30 Given: A solid sphere of mass m 0.60 kg and radius r 0.20 m is released from rest at the top of the incline shown. For this system, the coefficient of dynamic (sliding) friction is Hdyn 0.3 and the coefficient of static friction is Hstatic -0.5 Find: (a) Assume that the sphere rolls without slipping down the incline. Under this assumption, what is the acceleration of the sphere parallel to the incline, and how long does it...

A block is resting on a horizontal surface. The mass of the block is 40 kg. The coefficient of static friction between the block and the surface is us = 0.3 and the coefficient of kinetic friction is uk = 0.20. A man then decides to push on the block with 30 newtons of horizontal force. a) What is the acceleration of the block? Explain. b) Suppose the man pushes on the block with 200 newtons instead. What is the...
A mass (10 kg) slides up an inclined 10 degree surface at 5 m/s with coefficient of friction uk=0.5. It is connected by a cord over a pulley to a hanging 15 kg mass by a massless stretchfree cord. What is the acceleration of the mass on the incline? Direction of movement is up the incline and to the right.
a block of mass 10 kg is initially at rest when it slides down a frictionless incline whose height is 10 m and is pitched at an angle of 30 degrees. At the bottom of the incline the mass encounters a horizontal surface that has a coefficient of kinetic friction of 0.4 with the mass. How far from the bottom of the incline will the mass come to a stop?
