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 $\sin 37^\circ = 0.6$ and $\cos 37^\circ = 0.8$.

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?

Which of the following statements about a body thrown vertically upwards (no air resistance) is correct?
