Question

A drunk man was driving his car at speed of 25 m/s when he saw a cow in the middle of the road 50 m away from him. It took him .4 sec to react at which the car was moving at constant speed. after that, he stepped on the brakes to stop at the rate of 6 m/s. Is this acceleration enough to save him and the cow from an accident?

Answer 1

If the drunk man was driving at a speed of 25 m/s and the cow was 50 m away then it would take 2 seconds to impact the cow.

If it took him .4 seconds to react then it leaves him 1.6 seconds to brake and avoid a collision

The brakes stop at a rate of 6m/s so in the 1.6 seconds would slow down 9.6 m/s (6x1.6)

Which means the car would still be at a speed of 15.4m/s directly in front of the cow thus impossible to avoid an accident. The car would strike the cow at a speed of  15.4m/s.

At the speed the cow and driver is probably dead.

Answer 2

No, if the car is traveling at 25m/s and it takes four seconds to react to the cow that is 50m away, the car will travel 100m and  the cow would be in the backseat for two seconds b-4 he even starts to brake .
