Question

a car traveling at a velocity of 24 m/s is accelerated uniformly at a rate of 2 m/s for 8 secs . what's the final velocity?

Answer 1

The acceleration is 2 ms\(^{-2}\), or 2 metres per second per second. That means that for every second that passes, the speed increases by 2 ms\(^{-1}\). So if it's accelerating at 2 ms\(^{-2}\) for 8 s, how much extra speed is there? Now add that on to the original speed.

Answer 2

Kinematic equation v=u+at
v = final velocity, u= initial velocity, a = acceleration and t = time
