A runner has an acceleration of 10m/s(square). How long does it take him to reach a speed of 5m/s from rest?(note 'rest' means zero vilocity)

Give that:
Acceleration = 10m/s
Initial velocity = 0
Final velocity = 5m/s
Using acceleration formula:
a=(v-u)/t
10 = (5-0)/t
10t = 5
t = 0.5
So, it will take 0.5 s to reach the velocity of 5m/s
