If the displacement of a partcle is zero...

If the displacement of a partcle is zero, distance coverd.s

A

`y=x-5x^(2)`

B

`y=2x-5x^(2)`

C

`4y=2x-5x^(2)`

D

`4y=2x-25x^(2)`

Text Solution

Verified by Experts

The correct Answer is:
2
`u=sqrt(5)` and `tan theta=2`
so by `y=x tan theta-(gx^(2))/(2u^(2))(1+tan^(2) theta)`
`rArr y=2x-(10x^(2))/(2xx5) (1+4)rArr y=2x-5x^(2)`
