In the figure, a small block of mass m = 0.023 kg can slide along the frictionless loop-the-loop, with loop radius R = 13 cm. The block is released from rest at point P, at height h = 6.1R above the bottom of the loop. (a) How much work does the gravitational force do on the block as the block travels from point P to point Q? J (b) How much work does the gravitational force do on the block as the block travels from point P to the top of the loop? J If the gravitational potential energy of the block-Earth system is taken to be zero at the bottom of the loop, find the following. (c) the potential energy when the block is at point P J (d) the potential energy when the block is at point Q (e) the potential energy when the block is at the top of the loop J (f) If, instead of being released, the block is given some initial speed downward along the track, do the answers to (a) through (e) increase, decrease, or remain the same? increase decrease remain the same

In a truck-loading station at a post office, a small 0.200 kg package is released from rest at point A on a track that is one-quarter of a circle with radius 1.60 m (Figure 1). The size of the package is much less than 1.60 m, so the package can be treated as a particle. It slides down the track and reaches point B with a speed of 5.40 m/s. From point B, it slides on a level surface a distance of 3.00 m to point C, where it comes to rest. Figure 1 of 1 m = 0.200 kg Part A What is the coefficient of kinetic friction on the horizontal surface? Submit Request Answer Part B How much work is done on the package by friction as it slides down the circular arc from A to B ? Express your answer in joules. Submit Request Answer

A block of mass m = 4.00 kg, starting from rest, slides down a frictionless inclined plane (ramp) of length 3.00 m. The plane is inclined by an angle of θ = 25.0∘ to the ground. At the bottom of the plane, the block slides along a rough horizontal surface with a coefficient of kinetic friction μk = 0.200 until it comes to rest. Let y = 0 represent a position along this horizontal surface. a) What is the initial mechanical energy (kinetic plus potential) of the object? b) What is the speed of the block when it reaches the bottom of the ramp? c) What is the work done by the friction force? d) What is the magnitude of the friction force on the horizontal surface? e) How far does the object slide along the horizontal surface before stopping?
