Which best describes the speed of a ball as it is thrown straight up into the air and comes back down?
The ball goes up at a constant speed, stops, then comes down at a constant speed.
The ball goes up at a constant speed, stops, and increases speed as it comes down.
The ball goes slower and slower as it goes up, stops, and then goes faster and faster as it comes down.
The ball goes slower and slower as it goes up, stops, and then comes down at a constant speed.
This graph shows the distance a soccer ball has traveled versus time. Which type of motion could the data on the graph indicate?
The ball moved 5 m during a 10 s interval and then stopped moving.
The ball moved at a rate of 5 m/s throughout the time period of the graph.
The ball moved 5 m before the beginning of the graph and then stopped moving at 0 s.
The ball moved at a rate of 5 m/s before the beginning graph and then stopped moving at 0 s.
Why are new tires on a car better than older, worn tires?
