Question

How long will it take a car to accelerate from 15.2 m/s to 23.5 m/s if the car has an average acceleration of 3.2 m/s2?

Answer 1

Answer:

Initial Velocity (u) = 15.2 m/s

Final Velocity (v) = 23.5 m/s

Avg. Acceleration (a) = 3.2 m/s^2

Time taken will be = v = u+at

= 23.5 = 15.2 + 3.2t

= 8.3 = 3.2t

= 2.59 s = Time

Hope this helps.
