The range of a projectile is . Its kinetic energy will be maximum after covering a distance of:
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
The expression for a horizontal range of a projectile is, R=u2sin2θg here, θ is the angle of projection and u is the initial resultant velocity. The expression for kinetic energy is, KE=12mv2 For the maximum kinetic energy, the velocity should be…
