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.
Two rocks with different size and mass are dropped from the same height. Which of the rock will reach the ground first?
greater rock
smaller rock
both reach the ground at the same time

A cannon is fired horizontally from a 5.0 m tall tower. How much time will it take until the projectile hits the ground?
0.5 s
1.0 s

What is the relationship between motion in the x and y-dimensions?
If x is greater, then y is greater
If x is greater, then y is less
There is no relationship; independent
