You are racing some friends on bikes, but one of your friends cheats and gets a head start! they accelerate at a rate of 0.75 m/s2 for a total of 12 seconds. if they end with a velocity of 10 m/s, what was their initial velocity?

1 ms⁻¹

Explanation:

You can use the kinematic equation

which gives you the equation,

u = v - at

Where v = final velocity

           u = initial velocity

           a = acceleration

           t = time taken

u = 10 - 0.75×12

So you get u = 1 ms⁻¹
