Multiple Choice

You drop a ball and it falls for 3.3 seconds before hitting the ground. Assuming no air resistance, what is the velocity of that ball when it hits the ground if you're dropping it on the MOON? Equation: v = g x t

• 5.28 m/s down

• 32.34 m/s down

• 32.34 m

• 5.28 m/s/s/s

Multiple Choice

Mystery Planet X is similar to planet Earth. To orbit Planet X, you must have a speed of 6.1 m/s. If you want to escape the gravitational pull of Planet X, which speed could you go? (Escape velocity)

• 1.2 m/s

• 6.1 m/s

• 10 m/s

Multiple Choice

In the table shown, there is a list of planets (+ the sun), their masses, and the escape velocity. Based on this data, what is the relationship between mass and escape velocity?

• As mass increases, escape velocity increases

• As mass increases, escape velocity decreases

• Mass has no effect on escape velocity
