A driver on Route 15 is traveling at 50 mph (~22 m/s) when they
see a dog in the road ahead. The driver’s reaction time to apply
the brakes is 1.5 s. As the driver nears the dog they honk the horn
and thankfully the dog runs to safety on the side of the road. The
car finally comes to a stop 5 s after applying the brakes and 4 m
past where the dog had been standing. How far was the car from the
dog originally (when the driver first spotted the dog in the road)?
(Hint: you can assume that once the brakes are applied the
acceleration is constant.) Show equations used and a clear picture
and/or force diagram please.
