An object falls vertically from rest through air. The effect of air resistance cannot be neglected.

Which graph best represents the variation of the object's velocity with time?

An object is projected from a cliff edge at $v = 25\,\mathrm{m}\,\mathrm{s}^{-1}$ at a $37^\circ$ angle above the horizontal. It lands $82.4\mathrm{m}$ horizontally from the base of the cliff. What is the height of the cliff? Use and .

A boulder is dropped from the top of a cliff and simultaneously another is thrown horizontally from the same height with speed $v$. Both boulders land after $t$ seconds. Ignoring air resistance, what is the horizontal separation between the boulders when they land?

A projectile hits the ground at the same vertical level from which it was launched. Which of the following is a quantity that describes the entire duration of the projectile's motion, rather than a specific property at launch or landing?

A projectile is launched with initial velocity $v$ at angle $\theta$ and lands at the same height. At what point is the magnitude of its acceleration vector minimum?
