velocity changed by 20m/s in 10s. So that means an average acceleration of
(20m/s)/(10s) = (20/10) m/s^2 = 2 m/s^2
That is, every second, the velocity increased by 2 m/s, thus going from 0 to 20 in 10 seconds.
(20m/s)/(10s) = (20/10) m/s^2 = 2 m/s^2
That is, every second, the velocity increased by 2 m/s, thus going from 0 to 20 in 10 seconds.
