Conservation of Energy

A ball having kinetic energy KE, is projected at an angle of 60∘60^\circ from the horizontal. What will be the kinetic energy of ball at the highest point of its flight?

Show answer and solution

Answer: (c)

  1. At the top, KE=KE0cos⁡2θKE = KE_0\cos^2\theta.
  2. cos⁡260∘=14\cos^2 60^\circ = \frac{1}{4}
  3. So the answer is (c) KE4\frac{KE}{4}.
