Use the equation to solve the following problems. Show your work and make sure to include units
15. Calculate the acceleration of Josh riding his bicycle in a straight line that speeds up from 4 m/s to 6 m/s
in 5 seconds.
16. Dean is slowing down on his skateboard. He starts at a speed of 6 m/s and slows to 2.0 m/s over a time of
2 seconds. What is Dean’s acceleration?
17. A fish swimming at a constant speed of 1 m/s suddenly notices a shark appear behind it. Five seconds
later, the fish is swimming in the same direction at a speed of 4 m/s. Calculate the fish’s acceleration.
