A car is traveling at a speed of 80 ft/s when the brakes are suddenly applied, causing a constant deceleration of 10 ft/s2. Determine the time required to stop the car and the distance traveled before stopping.
This problem can be solved using the dynamic formulas for constant acceleration,
V = V0 + a*t
80 = 0 - 10*t
t = 8 seconds
The distance can be found,
V2 = V02 + 2as
802 = 02 - 2*10*s
s = 320 ft
So,
t = 8 s, s = 320 ft
