A pable of 0.10 g is thrown at a speed of 400 m/s. Find the work done to stop this pable.

A

40 J

B

4000J

C

8000J

D

3J

Text Solution

Verified by Experts

The correct Answer is:
C
Work done = Change in KE
`implies W = 1/2 mv^2 = 0`
`implies W = 1/2 xx 0.1 xx 400 xx 400`
`implies W = 8000 J`
