Answer:
a) The additional time required for the truck to
stop is 8.5 seconds
b) The additional distance traveled by the
truck is 230.05 ft
Explanation:
Since the acceleration is constant, the average
speed is:
(final speed - initial speed) / 2 = 0.75 v0
Since travelling at this speed for 8.5 seconds
causes the vehicle to travel 690 ft, we can solve
for vo:
0.75v0 * 8.5 = 690
vO = 108.24 ft/s
The speed after 8.5 seconds is: 108.24 /2 =
54.12 ft/s
We can now use the following equation to solve
for acceleration:
v2 – u? = 2 * a * s
54.122 – 108.24² = 2 * a * 690
a = -6.367 m/s^2
Additional time taken to decelerate: 54.12/6.367
= 8.5 seconds
Total distance traveled:
v² – u² = 2 * a * s
0 - 108 24^2 = 2-6 36 S

Total distance traveled:

O - 108.24^2 = 2 * (-6.367) * s
solving for s we get total distance traveled =
920.05 ft
Additional Distance Traveled: 920.05 - 690 =
230.05 ft
