1.

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))

Answer»

`0.196`
`19.6`
`-0.196`
`-19.6`

Solution :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,):}`
