The driver of a car traveling at 25m/s suddenly sees the lights of a barrier 45m ahead. It takes the driver 0.75s to apply the brakes and the acceleration during braking is –9.5 m/s2. Calculate whether the car will hit the barrier.
The car will hit the barrier
25x.75=18.75m + 32.38m = 51.64m

A car starts from rest and accelerates at 6.8 m/s2 for a period of 3.1s. The brakes are then applied and the car immediatly slows to a stop at the rate of -7.6m/s2. Calculate whether the car will hit a garbage can that is located 25m ahead of the position where the brakes were applied.
Car completely stops at 29.2 meters from when the brakes were applied. Garbage can was hit
