A 4.26-kg block starts up a 33.0˚ incline at 7.81 m/s. (a) How
far will it slide if it loses 34.6 J of mechanical energy due to
friction? (b) What is the coefficient of kinetic friction between
the block and the incline
An 18-kg sled starts up a 36 ∘ incline with a speed of 2.2 m/s .
The coefficient of kinetic friction is μk= 0.25.
How far up the incline does the sled travel?
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?
If the sled slides back down, what is its speed when it returns
to its starting point?

A block of mass m = 2.30 kg slides down a 30.0∘ incline which is
3.60 m high. At the bottom, it strikes a block of mass M = 6.20 kg
which is at rest on a horizontal surface (Figure 1). (Assume a
smooth transition at the bottom of the incline.) The collision is
elastic, and friction can be ignored.

the collision.
