Hello Dear,

◆ Complete question would be -

Q. A car moves in a circular path such that its speed is given by v = 4t where t is the time. If the radius of the circular path is 2 m, the acceleration of the car at t = 2 s is ___.

◆ Answer -

a = 32 m/s^2

◆ Explanation -

# Given -

v = 4t

r = 2 m

t = 2 s

# Solution -

Speed of car at t = 2 s is -

v = 4t

v = 4 × 2

v = 8 m/s

Centripetal acceleration at t=2s is calculated as -

a = v^2 / r

a = 8^2 / 2

a = 32 m/s^2

Hence, the acceleration of the car at t = 2 s is 32 m/s^2.

Hope this helped you..
