A block of metal weighing 2kg is resting...

A block of metal weighing 2kg is resting on a frictionless plane. It is struck by a jet releasing water at a rate of 1kg/s and at a speed of 5 m/s. Calculate the initial acceleration of the block.

A

`2.5m//s^(2)`

B

`5m//s^(2)`

C

`10m//s^(2)`

D

`5m//s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`F=(delm)/(delt)xx5`
`1=1kg//sxx5`
`therefore a=(5)/(2)=2.5 m//s^(2)`
