Problem 1
A small body of mass m is released from rest on a smooth straight ramp of length L inclined at angle α to the horizontal. The ramp ends at height h above a level floor, and the body leaves tangentially before landing. Neglect air resistance and take g=9.8 m/s². (a) Find the acceleration and travel time. (b) Find the speed and velocity components at the edge. (c) Determine flight time and horizontal range. Use SI units throughout and treat components as ideal exactly as specified. State sign conventions when writing equations and retain units in final results.

First identify the system, given quantities, and sign convention; this determines what is conserved or acts on the body. The stated idealizations exclude unmentioned forces or effects.
