Question

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.

Answer 1

At The Mars

Using equation of the motion

at maximum height V=0 So

.

.   ....1

Similarly for The Saturn' s moon

at maximum height V=0 so

Here v2 =1.15 v1

Using equation 1 and g2=0.264m/s/s

y2 =18.5350379 y1
