  4. D 100 m
Verified Solution

Answer & Solution

Correct Answer

(D) 100 m

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…
