A 2.0 kg wood block is launched up a wooden ramp that is inclined at a 29 ∘ angle. The block's initial speed is 11 m/s . The coefficient of kinetic friction of wood on wood is μk=0.200.

What vertical height does the block reach above its starting point? What speed does it have when it slides back down to its starting point?

Expert Solution

Consider the incline

--------------

Consider the block

When the block slides up the incline, initial kinetic energy is converted to potential energy but some portion of initial kinetic energy is lost due to friction.
