Suppose our experimenter repeats his experiment on a planet more massive than earth, where the acceleration due to gravity is g=30 m/s2. when he releases the ball from chin height without giving it a push, how will the ball's behavior differ from its behavior on earth? ignore friction and air resistance. (select all that apply.) mastering physics answers

Let the height of the chin is H from the floor

so the time taken by the ball to reach the bottom on the surface of earth is given by kinematics

now we will have time from above equation

here on earth the gravity is to be g = 10 m/s^2

now we will have

now for the surface of other planet time is given by

now we can find the ratio of two time

it shows that on the other planet where gravity is more the ball will take less time to reach the surface and will acquire more velocity when it will hit the floor

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)
