A 16-kg sled starts up a 28° incline with a speed of 2.4 m/s. The coefficient of kinetic friction is μk = 0.25. (a) How far up the incline does the sled travel? (b) What condition must you put on the coefficient of static friction if the sled is not to get stuck at the point determined in part (a)? (c) If the sled slides back down, what is its speed when it returns to its starting point?

A block with mass m is placed on the top of a smooth cline. The cline is h=4.7m high.
The block is released from the cline and the moves across a horizontal surface. The
region of the horizontal surface between A and B is tough and the kinetic friction
coefficient is μ = 0.47 and the distance between A and B is 0.6 meters. The
remained region of the horizontal surface is smooth. Then the block goes to a quarter
circle with radius R = 2.1m, The quarter circle is also smooth. Finally, the block
collide elastically with an identical mass, and the second mass flies from the quarter
circle and hits the ground. When the block hits the ground what is the horizontal
distance does it move in meters since it flies from the quarter circle?(g = 9.81m-s-2
