The driver is looking at her phone and has a total reaction time of 4.6 seconds as
the car is moving at a constant speed of 11 m/s. If the driver slams on her brakes
and slows down at a rate of -8.2 m/s?, what is the stopping distance for the car in
this situation?
A ball was thrown on top of a building, downwards towards the ground. The initial velocity of the ball is 2m/s. If the ball hits the ground 5 seconds after the throw, how tall is the building in meters? Assume that this is a classic free-fall problem.
tortoise crawls the entire 1000.0 meters at a speed of 0.20 m/s. The rabbit runs the
first 200.0 meters at 2.0 m/s, stops to take a nap for 1.3 hours, and awakens to
finish the last 800.0 meters with an average speed of 3.0 m/s. Who wins the race
and by how much time?
