How fast is the block traveling up the ramp

Reference no: EM13508520

A 3.00 kg block slides from rest from the bottom of an inclined plane, tilted up at 25 degrees. This acceleration is due to a tied string that goes up over a pulley attached to a 2.00 kg mass that falls from rest 2.00 m to the floor.

(a) How fast is the block traveling up the ramp when the falling block hits the floor if friction on the ramp is negligible?

(b) How fast is the block traveling up the ramp when the falling block hits the floor if the coefficient of friction on the ramp is 0.20? Use conservation of energy techniques.
