Evaluate the suitable answer of the following problem
Problem- a 2.6 kg wood block is launched up a wooden ramp that is inclined at a 30° angle. The block's initial speed is 14 m/s. (Use µk = 0.20 for the coefficient of kinetic friction for wood on wood.)
Part i- What vertical height does the block reach above its starting point?
Part ii- What speed does it have when it slides down to its starting point? m/s down the ramp.
Help me to calculate the suitable answer of the above problem.
