1. Hannah watches a thunderstorm from her living room window. She is concerned that the lightning may hit her house, and interrupt her IMing with her friends. She sees the flash of a lightning bolt and begins counting the seconds until she hears the clap of thunder 10.0 s later. Assume that the speed of sound in air is 340.0 m/ s. How far away was the lightning bolt a)in m? b) in km?

1. Hannah watches a thunderstorm from her living room window. She is concerned that
the lightning may hit her house, and interrupt her IMing with her friends. She sees the
flash of a lightning bolt and begins counting the seconds until she hears the clap of
thunder 10.0 s later. Assume that the speed of sound in air is 340.0 m/ s. How far away
was the lightning bolt a)in m? b) in km?
2. In the future, Hayden will win the Indianapolis 500 in 3.30 h. What will be his speed
during the 500 mile race?
3. The slowest animal ever discovered was a crab found in the Red Sea. It traveled with
an average speed of 5.70 km/ y. How long would it take this crab to travel 100 km?
How old would you be then?
4. Kristen is driving her red Lotus at 30 m/ s when a little doggie runs out in front of her.
Kristen slams on the brakes and comes to a stop in 3.0 s. (Narrowly missing the cute
little doggie! The dog's name was Lucky!) What was the acceleration of Kristen's car?
5. Spencer stands at the rim of the Grand Canyon and yodels down to the bottom.
(Spencer is a closet yodeler who yearns to travel to Switzerland!) Spencer hears his
yodel echo back from the canyon floor 5.20 s later. Assume that the speed of sound in
air is 340.0 m/.s. How deep is the canyon? (Hint: the time given is the time for the sound
to travel from Spencer's mouth, down to the bottom, and return back up to his ear.)
6. A jumbo jet taxiing down the runway receives word that it must return to the gate to
pick up an important passenger, Kyle, who was late for his connecting flight. The jet is
traveling at 45.0 m/ s when the pilot, Jamuara, receives the message. What is the
acceleration of the plane if it takes Jamuara 5.00 s to bring the plane to a halt?
7. Steven loves to run and has been training for years to break the "4-minute mile". He
finally reached his goal in Spain during the "running of the bulls"! Steven ran the mile in
3.81 minutes! During this amazing run, what was Steven's average speed in a)mi/ min?
b) mi/ h?
8. While driving her black Ferrari at 20.0 m/ s down highway 275, Katelynn comes up
behind Jack and decides to pass her in the left-hand lane. If Katelynn can accelerate
at 5.00 m/ s2, how long will it take for her to reach a speed of 30.0 m/ s and pass Jack.
9. Samantha is walking to the Sak's nail salon at a rate of 1.3 m/ s when she glances at
her Rolex and realizes that she is going to be late for her appointment! Samantha
quickens her pace at a rate of 0.090 m/ s2. a) What is Samantha's velocity after 10.0 s?
