A solid cylinder is released from rest and rolls without slipping down an inclined plane. A block with the same mass slides down another inclined plane, which is identical to the first inclined plane except that it is frictionless. If both the block and cylinder are released from the same height and at the same time, М. M o the cylinder will reach the bottom first. o the cylinder will reach the bottom with a greater kinetic energy, neither object...

019 10.0 points A block is released from rest, at a height h, and allowed to slide down an inclined plane. 1 There is friction on the plane. At the bottom of the plane, there is a spring that the block will compress. After compressing the spring, the block will slide up the plane to some maxi- mum height, hA, after which it will again slide back down. How much work is done on the block be- tween its release...

A block of mass M = 4.000 kg is released from rest at the top of an incline of angle θ = 24.0º w.r.t. the horizontal. The coefficient of kinetic friction between the block and the incline is µk = 0.200 and the length of the incline (hypothenuse of the triangle shown below) is L = 6.00 m. ( w.r.t. = with respect to) I am trying to find: a. The work done by the normal force for the complete...

long. The angle of the incline with respect to the horizontal
direction is and the coefficient of kinetic friction between the
block and the surfaces (incline and horizontal) is . The block
slides along the incline with constant velocity and continues
moving along the horizontal surface until it comes to rest. Using

(4) A block is released from rest slides down to the bottom of a plane of incline q from a height h; the block attains a speed Vbottom. An identical block is dropped and undergoes free-fall from the same height h and hits the ground with speed Vfree. (a) what is Vfree? (b) Since Vfree must be greater than Vbottom, calculate the coefficient of friction u between the block and the plane. [20 pts]
