A 2.0 kilogram wood block is launched up a wooden ramp that is inclined at a 30 degree angle. The block's initial speed is 10m/s. The coefficient of kinetic friction of wood on wood is µk .200.
Part A: Find what vertical height does the block reach above its starting point?
Part B: Find what speed does it have when it slides back down to its starting point?

Only two forces act on an object (mass=4.61 kg), as in the drawing. Find the direction (relative to the x axis) of the acceleration of the object
A 2.7-kg copper block is given an initial speed of 2.5 m/s on a rough horizontal surface. Because of friction, the block finally comes to rest. If the block absorbs 85% of its initial kinetic energy as internal energy, compute its increase in tempera..
