A car is moving with speed `30m//sec` on a circular path of radius 500 m . Its speed is increasing at the rate of , `2m//sec^(2)`, What is the acceleration of the car

A

`2m//"sec"^(2)`

B

`2.7 m//"sec"^(2)`

C

`1.8 m//"sec"^(2)`

D

`9.8 m//"sec"^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Net acceleration,
`a = sqrt(a_(t)^(2) + a_(r)^(2)) = sqrt((2)^(2) + (900/500)^(2)) = 2.7 m//s^(2)`
