A car moving at a speed of 70 kilometers per hour stops for 8 seconds. With what constant acceleration does the car move when braking?
Given:
V = 70km / h
t = 8c
To find:
a-?
SI:
V = 70000/3600 = 19.4m / s
Decision:
If the body moved uniformly throughout the entire path, i.e. with the same acceleration, then:
a = V / t = 19.4 / 8 = 2.65
