Conservation of Energy

A particle is projected making an angle of 45∘45^\circ with horizontal having kinetic energy KK. The kinetic energy at highest point will be

Show answer and solution

Answer: (b)

  1. At the top, speed =vcos⁡45∘= v\cos 45^\circ, so KE=Kcos⁡245∘KE = K\cos^2 45^\circ.
  2. KE=K×12KE = K \times \frac{1}{2}
  3. So the answer is (b) K2\frac{K}{2}.
