Work Power and Energy question

2023 · 6 Apr · Shift 2 · Q67

JEE MainPhysicsWork Power and EnergyNumerical+4 / −1
A body is dropped on ground from a height 'h1h_{1}h1​' and after hitting the ground, it rebounds to a height 'h2h_{2}h2​'. If the ratio of velocities of the body just before and after hitting ground is 4 , then percentage loss in kinetic energy of the body is x4\frac{x}{4}4x​. The value of xxx is ‾\underline{\hspace{2cm}}​.
