A particle moves along X-axis as
`x=4(t-2)+at(t-2)^(2)`
Which of the following is true ?

A

The initial velocity of particle is 4

B

The accekeration of particle varies with time

C

The particle is at origin at t = 0

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
D
` " "x=t (t-2) +(t-2) ^(2) rArr v= [2t -2+2(t-2) ]m//s and a= 4 m//s ^(2) `
` (4t-6)m//s " ", " "At t =0 , x =4 m and v = -6 m//s`
