A bullet fired into a trunk of a tree loses `1//4` of its kinetic energy in travelling a distance of 5 cm`. Before stopping it travels s further distance of

150 cm

`1.5 cm`

`1.25 cm`

15 cm

Text Solution

Verified by Experts

The correct Answer is:

`(4)`

`W = overline F. overline S = Delta KE (S_(1))/(S_(2)) = (Delta KE_(1))/ (Delta KE _(2))`
