If the kinetic energy of 1 kg mass is 1 ...

If the kinetic energy of 1 kg mass is 1 J then its velocity is

A

`sqrt(2) ms^(-1)`

B

`2 ms^(-1)`

C

`1/(sqrt2) ms^(-1)`

D

`1/2 ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
We know that, K.E.= `1/2 mv^2`
`1 = 1/2 xx 1 xx v^2 implies v^2 = 2 implies v = sqrt(2)ms^(-1)`
