 Homework Statement
 Planet A and Planet B have the same mass, but planet A is twice larger than planet B. A ball dropped above the surface of planet A has an acceleration due to gravity of 10 m/s^2. which of the following is true if a ball is dropped 100 m from the surface of planet A.
 Homework Equations

A. If the ball is dropped 100 m from the surface of planet B, it will reach the ground at the same length of time it does at planet A.
B. at 1 s of its fall, the speed of the ball at planet A is less than the speed of the ball at planet B
C. the acceleration of the ball at planet A exceeds the acceleration of the ball at planet B.
D. the distance traveled by the ball at planet A is twice the distance traveled by the ball at planet B.
Choice D is obviously wrong therefore leaving us with choices A, B, and C. Can someone explain the relationship of the three variables stated above (mass, volume, and acceleration due to gravity)? Thank you.
