You throw a ball into the air. You catch the same ball 6 seconds later. What was the ball's maximum height?

• 44.1 Meters
• 88.2 Meters
• 22.1 meters
• Impossible to determine

A train travels 6 meters in the first second of travel, 6 meters again during the second second of travel, 6 meters again during the third second.  It's acceleration is __  m/s^2?

• 0
• 6
• 12
• 18

A  car starts from rest and after  7 seconds it is moving at 42  m/s. What is the ’s average acceleration?

• 0.17
• 1.67
• 6
• 7

An object  accelerates at 2  m/s^2. Assuming the object starts from rest, how much time does it need to accelerate to a speed of 16  m/s?

• 4 s
• 8 s
• 16 s
• 1/16 s

A car is traveling at 21.0 m/s. It slows to a stop at a constant rate over 5.00 s. How far does the car travel during those 5.00 seconds before it stops? 

• 4.20 m
• 52.5 m
• 105 m
• 158 m

What happens to the velocity of a ball as it is dropped off a cliff? 

• It decreases at a uniform rate 
• It increases at a uniform rate 
• It is constant 

If a bunny hops at 2 m/s, how long does it take him to go 5 m?

• 2.5 s
• 10 s
• .4 s
• 2 s
