Problem
A laboratory launcher fires small steel pellets with the same initial speed u but at various angles above the horizontal in an otherwise identical environment. Air resistance is negligible and the pellets land at the same vertical level from which they were launched.
(a) Predict which pair of launch angles will give equal horizontal ranges and explain your reasoning.
(b) Describe how the shape of the trajectory changes as the launch angle is increased from 0∘ to 90∘ while the initial speed remains fixed.
(c) Explain qualitatively how the set of horizontal ranges would be affected if the experiment were repeated on a planet where the free-fall acceleration is larger than on Earth.
