B. Divide the mass of the object by its velocity.
C. Multiply the mass of the object by its height.
D. Divide the mass of the object by its height.

3. Which of the two balls (soccer ball and baseball) has a greater kinetic energy when thrown on the ground?

A. Soccer ball, because it's bigger than baseball.
B. Soccer ball, because it has more mass.
C. Baseball, because it is smaller.
D. Baseball, because it has less mass. of 4m/s.
