How far does it travel during the second second?

Starting from rest, a boulder rolls down a hill with constant acceleration and travels 4.00 during the first second.


How far does it travel during the second? How fast is it moving at the end of the first second? How fast is it moving at the end of the second second?|||At the end of the first second the speed is the distance traveled divided by the time so 4/1= 4m/s or 14.4km/h





If it accelerated from 0m/s to 4m/s in 1s the the acceleration= 4m/s^2 (4/1) or 14.4km/h^2





If the acceleration is constant then in 2 seconds it will be going 8m/s (4x2) or 28.8km/h
