Multiple Choice
What is the acceleration of a ball that is dropped off the side of a cliff after 1,2,3,4,5 seconds? (assume g is rounded to 10 m/s2)
5,10,15, 20, 25 m/s2
10, 20, 30, 40, 50 m/s2
5, 20, 45, 80, 125 m/s2
10,10,10,10,10 m/s2

Multiple Choice
What is the vertical velocity of a ball that has been dropped off a cliff after 1 , 2, 3, 4, and 5 seconds? (assume g is rounded to 10 m/s2)?.
10, 20, 30, 40, 50 m/s
5, 10, 15, 20, 25 m/s
5, 20, 45, 80,125 m
10,10,10,10,10 m/s
3.
Multiple Choice
How does the initial vertical velocity, Viy, compare to the final vertical velocity, Vfy, when a ball is thrown up into the air and caught at the same height ?
Vi y and Vfy are exactly the same, this is because of symmetry
Viy and Vfiy are close but Vfy is larger because you would fall faster than you would rise, since you are slowing down
Viy and Vfy are the same in magnitude, but different in direction.
Viy and Vfy are different in magnitude and direction.
4.

initial velocity
final velocity
acceleration
displacement
5.
