The displacement is given by x = 2t^(2)...

The displacement is given by ` x = 2t^(2) + t + 5` , the acceleration at t = 5 sec will be-

A

`8 "m/s"^(2)`

B

`12 "m/s"^(2)`

C

`15 "m/s"^(2)`

D

`4 "m/s"^(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`{:("Displacement", x=2t^(2)+t+5),("Velocity",V=(d^(2)x)/(dt^(2))=4t+1),("Acceleration",a=(dv)/(dt)=4"m/s"^(2)):}`
