Rock and range

  1. Sep 14, 2013 #1
    1. The problem statement, all variables and given/known data
    Assuming that the rock launched by a catapult is released from ground level, show that the theoretical maximum range is:
    R=2Mh/m, where M = mass of counterweight
    m = mass of rock
    h = height counterweight falls


    2. Relevant equations

    Ep=mgh
    Ek=(mv^2)/2

    3. The attempt at a solution

    I equated the two expressions and then split the velocity into its components so this splits the Ek up into horizontal and vertical but I cant progress from here

    At what angle should a projectile be launched to obtain a maximum range?
     
  4. Sep 14, 2013 #3
    45degrees

    What is the range when the angle is 45 degrees and the magnitude of velocity is some v?
