A particle of mass `0.2` kg is moving is one dimension under a force that delever is a constant preses `0.5 W` in the particle . If the detail speed `(n ms^(-1))` of the particle is zero , the speed`(mms^(-1))` after `5 xx` is |
|
Answer» Here `Delta K.E. = W = P xx t ` `:. (1)/(2) mnu^(2) = P xx t ` `:. Nu = sqrt (2Pt)/(m) = sqrt(2 xx 0.5 xx 5 )/(0.2)) = 5 ms^(-1) ` |
