In 1985, Said Aouita set the world record
for the 1500 meter race in a time of 3 minutes and 29.46 seconds.
What was his average velocity?
Sound travels at a constant speed of 343
m/s in air. Approximately how long does it take for the sound of
thunder to travel 1609 meters (i.e., one mile)?
A sporty sports car can go from rest to
32 m/s in 9.0 seconds. So what is its average acceleration?
A sprinter accelerates to a velocity of
5.36 m/s in 3.00 s. His average acceleration is 0.640 m/s2.
What was his velocity when he first started accelerating?
In getting ready to slam-dunk the ball,
a basketball player starts from rest and sprints to a speed of 6.0 m/s
in 1.5 s. Assuming he accelerates uniformly, how far does he travel
in this time?
A soccer player running at a speed of 2.6
m/s decides to accelerate. For the next 18 m he speeds up with an
acceleration of 0.45 m/s2. What is his speed at the end of the run?
A ball is thrown upward with an initial
speed of 35 m/s. What is its speed 2 seconds later?
