Acceleration Test Review

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. 

This graph demonstrates an object that is -

• At a constant speed
• Increasing speed
• Decreasing speed
• Stationary

This graph demonstrates an object that is -

• At a constant speed
• Increasing speed
• Decreasing speed
• Stationary

What is this graph showing?

• Constant Speed

• Speeding up

• Slowing down

• No motion

A parachute on a racing dragster opens and changes the speed of the car from 85 m/s to 45 m/s in a period of 4.5 seconds. What is the acceleration of the dragster?

______ m/s/s

While traveling along a highway a driver slows from 24 m/s to 15 m/s in 12 seconds. What is the car's acceleration in m/s/s?

A car traveling at a speed of 30.0 m/s encounters an emergency and comes to a complete stop. How MANY SECONDS for the car to stop if it decelerates at -4.0 m/s/s?

A cart rolling down an incline for 5 seconds has an acceleration of 4.0 m/s2. If the cart has a beginning speed of 2.0 m/s, what is the final speed in m/s?

Which of the following would be considered an acceleration?

• An object speeding up

• An object moving with a constant velocity

• An object slowing down

• An object standing still

• An object changing direction

Why does a car accelerate as it round a corner at a constant speed?

• Its direction changes
• It doesn't
• It slows down
• Its speeds up
