A stone is dropped from a height h. It hits the ground with a certain momentum P. If the same stone is dropped from a height `100 %` more than the previous height, the momentum when it hits the ground will change by -

A

`8/3`

B

`3/8`

C

`sqrt(3)`

D

`2/sqrt(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
Max. height `H=(u^(2) sin^(2) theta)/(2g),(10xx(sqrt(3)/2)^(2))/(2xx10)=3/8 m`
