Answer:
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.
