Asked by Steph

A driver in a car traveling at a speed of
72 km/h sees a cat 107 m away on the road.
How long will it take for the car to accelerate uniformly to a stop in exactly 104 m?
Answered by Damon
72 km/hr *1000/3600 = 20 m/s

average speed during acceleration = (20+0)/2 = 10 m/s

104 = 10 m/s * time to stop
so
time = t = 10.4 seconds
