Amotorist traveling at 15 m/s encounters a deer in the road 46 m ahead. if the maximum acceleration the vehicle’s brakes are capable of is −7 m/s 2 , what is the maximum reaction time of the motorist that will allow her or him to avoid hitting the deer?

2 seconds

Explanation:

Acceleration = a = -7 m/s²

u = Initial velocity = 15 m/s

v = Final velocity = 0

Distance the car will travel after hitting the brakes = s

Distance to the deer = 46 m = s₁

Time it takes the car to stop = t

From equation of motion

Maximum reaction time would be 2 seconds.
