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.

The equation follows by applying the physical law to the chosen system; ideal constraints link the variables. Signs must remain consistent with the defined directions.
