(a) the velocity of the car before the brakes were
applied is given;
v? = u? + 2ad
v² = 0 + 2(10 x 300)
v? = 6000
V = v6000
v = 77.46 ft/s
(b) the time required for the car to stop
d = ut + /½at?
d = 0 + /½at?
d = /½at?
t? = 2d / a
t = v ( 2d / a)
t= v (2 x 300 / 10)
t = 7.8 s
Therefore, the time required for the car to stop
is 7.8 s
