Position of a particle moving along x-ax...

Position of a particle moving along x-axis is given by `x=2+8t-4t^(2)`. The distance travelled by the particle from `t=0` to `t=2` is:-

Text Solution

Verified by Experts

The correct Answer is:
`36 m`
`S_(n)=u+a/2 (2n-1)` by putting the value of `n=7` and 9, find the value of u & `a, u=7 m//s` & `a=2 m//s^(2)`.
