you are sledding on a snow-covered hill at a speed of 6 m/s there is a drop that increases your speed to 12 m/s in 4 s. find your acceleration? i need help answer?

• science -

since v changed by 6m/s in 4 s, a = 6/4 = 1.5 m/s^2

That is, every second, v increased by 1.5 m/s. After 4 seconds, it had increased by 6 m/s, from 6 to 12.
