A.) They are parallel to each other

B.) They are not related to each other at all

C.) They are perpendicular to each other

Two vectors are given so that Vector A + Vector B = 0, describe magnitude and direction.

A.) Different Magnitude, Different Directions

B.) Same Magnitude, Different Directions

C.) Same Magnitude, Same Directions

A projectile is launched from ground at 30 degrees. At what point in trajectory does projectile have least speed?

A.) The highest point

B.) The midpoint

C.) The lowest point

In this problem: “You have two balls and from the same height (and same time), one ball (Ball #1) is dropped and another (Ball #2) is fired horizontally. which ball hit the ground first?” Which ball has greater final velocity at ground level?

A.) Ball #1

B.) Ball #2

C.) They have the same final velocity
