Acceleration Practice

A roller coasters accelerates from an initial velocity of of 6.0 m/s to a final velocity of 70 m/s over 4 seconds.  What's the acceleration?

• 24 m/s²
• 18 m/s²
• 16 m/s²
• 16 m/s

• m/s²
• mi/hr
• ft

Acceleration is

• the rate at which velocity changes.

• the change in velocity

• the rate of change

• when you speed up only

Which of the following is a unit for acceleration?

• km/s
• m/s²
• mi/hr
• ft

If velocity is measured in meters/second and time is measured in seconds, the unit of acceleration is

• m/s/s

• m/s²

• m/s

• m
