10 Problem 5A dragster in a race accelerated from stop to 60 m/s by the time it reached the finish line. The dragster moved in a straight line and traveled from the starting line to the finish line in 8.0 sec. What was the acceleration of the dragster?
12 Problem 6Toon Train is traveling at the speed of 10 m/s at the top of a hill. Five seconds later it reaches the bottom of the hill and is moving at 30 m/s. What is the rate of acceleration of Toon Train?
13 Answer 630 m/s - 10 m/s = 20 m/s ÷ 5 s = 4 m/s2
14 Problem 7Pete the Penguin loves to sled down his favorite hill. If he hits a speed of 50 m/s after 5 seconds, what is his rate of acceleration?
15 Answer 750 m/s - 0 m/s = 50 m/s ÷ 5 s = 10 m/s2
16 Problem 8Monster Mike’s truck decelerates from 72 m/s to 0 m/s in 6 seconds. What is his rate of deceleration?
17 Answer 80 m/s - 72 m/s = - 72 m/s ÷ 6 s = -12 m/s2
