A particle of mass `0.2 kg` is moving in one dimension under a force that delivers constant power `0.5 W` to the particle. If the initial speed (in `ms^(-1)`) after `5s` is.

Text Solution

Verified by Experts

The correct Answer is:
`5`
`(1)/(2) m upsilon^(2) - (1)/(2) m u^(2) = W`
`(1)/(2) mv^(2) = Pt`
`upsilon = sqrt((2Pt)/(m)) = sqrt((2 xx 0.5 xx 5)/(0.2)) = 5ms^(-1)`.
