Answer #1

Time period of a pendulum,   where l is length of pendulum and g is acceleration due to gravity.

From above formula, we see

Let time period on Earth be and time period on Moon be while be acceleration due to gravity on Earth and be acceleration due to gravity on Moon.

Required ratio is 0.6

An object is thrown vertically upward from the surface of Mars, where the acceleration due to gravity is ?1=3.70 m/s2.g1=3.70 m/s2. The initial velocity is ?1,v1, and the object reaches a maximum height of ?1.y1. What is the maximum height, ?2,y2, if the object is thrown with a speed of ?2=1.15?1v2=1.15v1 from the surface of Saturn's moon Rhea? The acceleration due to gravity on Rhea is ?2=0.264 m/s2.g2=0.264 m/s2. Give your answer as a multiple of ?1.
