A particle is moving on a straight line ...

A particle is moving on a straight line with velocity (v) as a function of time (t) according to relation `v = (5t^(2) - 3t + 2)m//s` . Now give the answer of following questions :
Velocity of particle when acceleration is zero is :

A

`1 m//s`

B

`(35)/(20)m//s`

C

`(31)/(20)m//s`

D

`38m//s`

Text Solution

Verified by Experts

The correct Answer is:
C
Velocity of …………….
`a = 10t - 3 = 0`
`t = (3)/(10)`
`V = ((3)/(10))(2)/(3)`
`V_((t= 3//10))= 5((3)/(10))^(2)-3 ((3)/(10))+2 = (31)/(20)m//s`
