Acceleration Review

A golf ball accelerates off a tee at 15m/s², changing its velocity from 0m/s to 50 m/s down the fairway. How long did it take the golf ball to accelerate?

• 750 seconds
• 35 seconds
• 0.3 seconds
• 3.3 seconds

A ball of clay is thrown at a wall at a velocity of 28.0 m/s.  After it hits the wall, it takes 0.020 s to stop.  What is the acceleration of the clay when it hits the wall?

• 1400 m/s²
• -1400 m/s₂
• 0.56 m/s²
• -0.56 m/s²

A box sliding down an inclined plane attains a velocity of 27 m/s in 3 seconds from rest.  Find the acceleration.

• 30 m/s
• 24 m/s²
• 9 m/s²
• 81 km/hr

How fast is the car traveling at 30 seconds?

• 5m/s
• 10m/s
• 20m/s
• 30m/s

The picture of the position vs. time graph shows an object that is...

• accelerating/speeding up
• moving at a constant speed 
• not moving 
• accelerating/slowing down. 

Acceleration is defined as the CHANGE in 

• time it takes for one place to move to another place. 
• velocity of an object.
• distance divided by the time interval 
• velocity divided by the time interval 

Acceleration only takes place when things speed up. 

• True
• False

Determine the motion of the car.

• at rest 
• moving at constant speed
• speeding up
• slowing down

Which graph shows the object standing still?

• A
• B
• C
• D

Which graph demonstrates the greatest positive speed?

• A
• B
• C
• D
