A bullet fired into a fixed target loses half of its velocity after penetrating 3 cm. How much further it will penetrate before coming to rest assuming that it faces constant resistance to motion ?

A

3.0 cm

B

2.0 cm

C

1.5 cm

D

1.0 cm

Text Solution

Verified by Experts

The correct Answer is:
d
Since time in both cases will be same.
`:.`During retarded motion, distance convered in equal intervals of time are `x_1:x_2=3:1`
`:.(x_1)/(x_2)=(3)/(1)implies x_2=(3)/(3)=1cm`
