3. Josh rolled a bowling ball down a lane in 2.5 s. The ball traveled at a constant acceleration of 1.8 m/s2 down the
lane and was traveling at a speed of 7.6 m/s by the time it reached the pins at the end of the lane. How fast was
the ball going when it left Tim’s hand?

4. A lizard accelerates from 2 m/s to 10 m/s in four seconds. What is the lizard’s average acceleration?
5. Goldie, a goldfish, is a speed swimmer. The park’s pond is &frac12; of a kilometer long. If she can swim 20 laps
around the pond in two hours, what is her average speed?
6. Falling objects drop with an average acceleration of 9.8 m/s2. If an object falls from a tall building, how long

7. If you shout into the Grand Canyon, your voice travels at the speed of sound (340 m/s) to the bottom of the
canyon and back, and you hear an echo. How deep is the Grand Canyon at a spot where you can hear your
echo 5.2 seconds after you shout?
8. It takes Stu, a slimy slug, 20 minutes to travel from his favorite bush to the local trash can (a trip of 30 meters).
How far can he travel in one hour?
9. A roller coaster car rapidly picks up speed as it rolls down a slope. As it starts down the slope, its speed is
4 m/s, but three seconds later, at the bottom of the slope, its speed is 22 m/s. What is its average acceleration?
10. A cyclist accelerates from 0 m/s to 8 m/s in three seconds. A car accelerates from 0 to 30 m/s in eight seconds.
Which has the higher rate of acceleration, and what is the rate?
11. Pete the penguin loves to sled down his favorite hill. If he hits a speed of 50 m/s after five seconds, what is his
rate of acceleration? [hint – he starts at 0 m/s at the top of the hill]
12. If a Ferrari, with an initial velocity of 10 m/s, accelerates at a rate of 50 m/s2 for three seconds, what will its final
velocity be?
13. Monster Mike’s truck decelerates from 72 m/s to 0 m/s in six seconds. What is his rate of deceleration?
14. At exactly 2:00 pm, Speedy the snail craws onto a meter stick at the 10 cm mark. If he reaches the 65 cm mark
at exactly 2:10pm, what is his speed?
