Th figure below shows a mass m=1.0 kg which is initially moving
with speed v=7.2 m/s at the top of a frictionless hill of height
h=4.9 m. It slides down the hill until it encounters a flat section
with unknown coefficient of kinetic friction µk. If the object
travels a distance D=11.1 m before reaching a speed of v/2, what is
the coefficient of kinetic friction µk? (use picture, but first
question)

A large rough ramp is inclined φ=35 degrees above the horizontal. A block of mass m = 5 kg is sliding on the board and the coefficient of kinetic friction between the block and the ramp is μk=0.3 . The block is tied to a string of length L = 0.25 meters so that the block moves about a circular trajectory. HINT: I'd recommend drawing the FBDs from a side-view. a) Draw a complete FBD of the block at the...
