Calculate the time (in seconds) needed for a car to accelerating from 0 m/s to 10 m/s at 5 m/s^2?

Answer: 2 s

Explanation: In order to solve this problem we have to use the formule of the final speed getting with a constant acceleration, it is given by;

Vfinal=Vo+a*t where Vo is zero.

so then t=Vfinal/a = (10 m/s) / 5 m/s^2 = 2 s
