A monkey sitting on a tree at a height of 19.6 m, drop a 10 g seed of rose apple on a crocodile, at rest below the tree. If the seed falls in the mouth of the crocodile in 2 s time and becomes stationary, then the momentum gained by the crocodile (in addition to the seed) is........... kg m/s. `(g=9.8ms^(-2))`

A

`0.196`

B

`19.6`

C

`-0.196`

D

`-19.6`

Text Solution

Verified by Experts

The correct Answer is:
A

momentum gained by crocodile
`{:(p=mv,|,"Where "v=V_(0)+"gt"),(=10xx10^(-3)xx19.6,=0+9.8xx2,),(therefore p=0.196kgm//s,=19.6m//s,):}`
