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

• The crumpled paper because its shape allows for less air resistance slowing the paper.

• The flat paper because its shape allows for less air resistance slowing the paper.

• Both pieces of paper will hit the ground at the same time because they are the same mass.

• More information is needed

Two balls that look the same, but have different masses are dropped at the same time from the top of the ladder. Which ball will hit the ground first?

• The ball with the most mass because it has less air resistance slowing the paper.

• The ball with the most mass because it has more air resistance slowing the paper.

• Both pieces of paper will hit the ground at the same time because the acceleration due to gravity is a constant (Stays the same).

• More information is needed

Which equation would you use to find the acceleration of an automobile whose speed decreases from 100 m/s to 5 m/s in 20s?

• (100m/s-5m/s) / 20s = 4.75m/s²

• (100m/s+5m/s) / 20s = 5.25m/s²

• (5m/s-100m/s) / 20s = -4.75m/s²

• (5m/s-100m/s) = -95m/s
