Question

A body is moved along a straight line by a machine delivering a power proportional to time `(P prop t)`. Then, match the following.

Answer 1

Correct Answer - `(A to p, B to q, C to q)`
`P prop t`
`W=intPdt=int alpha tdt " or "W prop t^(2)`
Since, work done is equal to change is KE
`"Hence"," " v^(2) prop t^(2) " or "v prop t``W=intPdt=int alpha tdt " or "W prop t^(2)`
Further, `" " v=(ds)/(dt)`
`:. (ds)/(dt) prop t " or "ds prop t dt " or "s prop t^(2)" "("by integration")`
