Acceleration

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

A car starts from rest at a stop light and reaches 20 m/s in 3.5 s. Determine the acceleration of the car.

• 2.2m/s²
• 7.0m/s²
• 5.7m/s²
• 70m/s²

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

In each of the following cases, determine where the car has no acceleration ?

• A car shortly after a stoplight turns green.
• A car approaching a red light
• A car with the cruise control set at 80 km/h
• A car turning a curve at a constant speed

Which of the following is a unit for acceleration?

• km/s
• m/s²
• mi/hr
• ft

When are you undergoing an acceleration in a car? 

• speed up
• slow down
• make turns
• All of the above 

What car has the fastest acceleration?

• Car goes from 0-60 Mph in 3 seconds
• Car goes from 0-60 Mph in 4 seconds
• Car goes from 0-60 Mph in 5 seconds
• Car goes from 0-60 Mph in 6 seconds

A drag racer accelerated from 0 m/s to 200 m/s in 5 s.  What was the acceleration?

• 0 m/s
• 40 m/s²
• -40 m/s²
• 40 m/s

The SI unit for acceleration is

• mph

• ft/sec

• m/s²

• m/s
