The position of a particle is represented by the following equation.
`x=3t^(3)+7t^(2)+5t+8`
where x is in metres and t in seconds. Find the acceleration of the particle at t = 1 s.
Strategy : `v=(dx)/(dt) and a=(dv)/(dt)`

A

`(10, 6, 0) m`

B

`(8, 6, 0)m`

C

`(10, 8, 0) m`

D

`(6, 10, 0)m`

Text Solution

Verified by Experts

The correct Answer is:
A
`PQ=R=(u^(2) sin 90^(@))/(g)=(100xx1)/(10)=10 rArr PQ=10`

`(x,y)=(10, 6, 0)`
