Two packages at UPS start slidingdown the ramp shown in the figure. Package A has a mass of 5.50 anda coefficient of kinetic friction of 0.210. Package B has a mass of10.5 and a coefficient of kinetic friction of 0.160.
How long does it take package A to reach the bottom?

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 (the figure (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 4.00m/s. From point B, it slides on a level surface a distance of 3.00 m to point C, where it comes to rest.

1-What is the coefficient of kinetic friction on the horizontal surface?

2-How much work is done on the package by friction as it slides down the circular arc from A to B?

A block of 250 g rest against a spring at the bottom of a ramp that is inclined at 35.0 degrees with the horizon. The spring is initially compressed 18.0 cm and the coefficient of kinetic friction between the block and the ramp is 0.210. When the spring is released, the block slides up the ramp. At what height above the point of release does the block come to rest on the ramp? ( answer is 1.53m just have no idea how to get there)

The figure shows a 1.75-{\rm kg} block at rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 10.0 {\rm cm} that has a coefficient of kinetic friction 0.650.Find h such that the block's speed after crossing the rough patch is 3.10 {\rm m/s}.
