• 1.
A ball is dropped from the top of a tall building. It falls through the air for 4.0 seconds before hitting the ground. Knowing that all falling objects accelerate at a rate of 10. meters per second squared, how tall is the building?
• 2.
A hawk is flying at an altitude of 234 meters above the ground. It drops a mouse that it had been carrying. Knowing that all falling objects accelerate at a rate of 10. meters per second squared, calculate the time it will take for the mouse will fall through the air before hitting the ground.
• 3.
A car accelerates at a steady rate of 3.00 meters per second squared travelling north for 5.00 seconds. Calculate the distance the car traveled in that time.
• 4.
A marble is dropped from a table that is 1.25 meters tall. Knowing that all falling objects accelerate at a rate of 10 meters per second squared, calculate the time it will take for the marble to hit the floor.
• 5.
Watch the first one minute and thirty seconds of this video: http://www.youtube.com/watch?v=HXOcYExulKk In the first 37 seconds, what happens to Felix Baumgartner's velocity as he is falling?
• A.

His velocity increases steadily as he falls

• B.

His velocity decreases steadily as he falls

• C.

His velocity stays the same as he falls

• D.

His velocity fluctuates wildly as he falls

• 6.
After falling for approximately 1 minute, Felix Baumgartner begins to decelerate. Why?
• A.

He has opened a parachute, causing him to slow down rapidly.

• B.

He has entered a lower layer of the atmosphere where the air is thicker, causing more air resistance (friction) that slows down his fall.

• C.

He has broken the sound barrier, which causes objects to slow down rapidly.

• D.

The air closest to the earth is less dense because of solar heat that is reflected off of clouds.

• 7.
Felix Baumgartner's initial altitude was approximately 39,000 meters above the earth. According to our formula, the time of his fall should have been about 88 seconds, but it took him more than 9 minutes (540 seconds) to reach the ground. Why?
• A.

He must not have been as high up as was reported.

• B.

He had a special suit that allowed him to breath in outer space.

• C.

He was slowed down by the speed of sound.

• D.

Air resistance makes it impossible for falling objects to actually reach an acceleration of 10 meters per second squared.
