A ball is dropped from some height and after first collision with the ground if it reaches \(\frac{3}{4}^{\text {th }}\) of its original height, then the \(\%\) loss of its energy.
- A \(25\)
- B \(75\)
- C \(50\)
- D \(55\)
Answer & Solution
Correct Answer
(A) \(25\)
Step-by-step Solution
Detailed explanation
Let a ball is dropped from height \(\mathrm{h}\) then initial potential energy \(U_i=m g h\) Final height \(=\frac{3}{4} h\) then final potential energy, \(U_f=\frac{3}{4} \mathrm{mgh}\) The percentage loss of its energy…
