Speed and Acceleration Problems

A roller coasters accelerates from an initial velocity 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

What is speed?

• how far you go

• how much distance is covered over a period of time

• how fast you accelerate

• the change in the location of a object
