Homework Help: Finding the maximum height given multiple variables

  1. Sep 14, 2012 #1
    1. The problem statement, all variables and given/known data

    A 4.27-kg object is thrown vertically upward from the surface of Mercury, where the acceleration due to gravity is g1 = 3.70 m/s2. The initial velocity is v1, and the object reaches a maximum height of y1. What is the maximum height, y2, if the object is thrown with a speed of v2 = 1.99v1 from the surface of Saturn\'s moon Iapetus? The acceleration due to gravity on Iapetus is g2 = 0.223 m/s2. Give your answer as a multiple of y1.

    2. Relevant equations
    Vf2- Vi2 = 2a∆y

    3. The attempt at a solution
    y2=29.30 y1

    Hi kaitwhit, Welcome to Physics Forums.

    Try using the x2 and x2 buttons on the edit panel header to create superscripts and subscripts in your equations :wink:

    Can you show the work you did to arrive at your result so that we can know how to help?
