What do we have to do in order to find change in speed (Delta v) in the acceleration equation.

• Final Speed - Starting Speed
• Starting Speed - Final Speed

What do we divide by in the acceleration equation?

• Starting Speed
• How long it took to accelerate
• Final Speed

A roller coaster car is traveling 6 m/s at the top of the track. At the bottom of the track,5 seconds later, it is traveling 36 m/s. What do you do first to find the answer?

• Subtract 6 - 36
• Subtract 36 - 5
• Subtract 36 - 6
• Subtract 5 - 36

A roller coaster car is traveling 6 m/s at the top of the track. At the bottom of the track,5 seconds later, it is traveling 36 m/s. What is the second step?

• Divide 30 by 5
• Divide 31 by 5
• Divide - 30 by 5
• Divide -31 by 5

• More information is needed to determine which ball will hit the ground first.
• The crumpled ball of paper will hit the ground first.
• Both pieces of paper will hit the ground at the same time.
• The smooth, flat piece of paper will hit the ground first.

Two pieces of paper that are the same size and mass are dropped at the same time from the top of the ladder. One is flat and the other crumpled into a ball. Which piece of paper will hit the ground first? EXPLAIN.

• We don't have enough information in order to know which will fall first.

• The crumpled paper will fall faster because there is less air resistance from the surface slowing its motion

• The smooth, flat paper will hit the ground first because there is more surface area for gravity to pull on and it will fall harder,
