The displacement s of a point moving in ...

The displacement `s` of a point moving in a straight line is given by:
`s = 8 t^(2) + 3t - 5`
`s` being in cm and `t` in s. The initial velocity of the particle is:

A

3 unit

B

`-3` unit

C

5 unit

D

`-5` unit

Text Solution

Verified by Experts

The correct Answer is:
A
`s = 8t^(2) + 3t - 5, (ds)/(dt) = 16 t + 3`
Initial velocity , `u=(ds)/(dt)|_(t=0)=3` unit
