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 =0 then the final speed (in `ms^(-1)`) after `5s` is.

Text Solution

Verified by Experts

The correct Answer is:
`(5)`
`Power=(dW)/(dt)impliesW=0.5xx5=2.5=KE_f-KE_i`
`2.5=M/2(v_f^2-v_i^2)rarrv_r=5`
