    Kinematics of pumpkin shot out of air cannon

    okay figured it out i ended up having to set separate variables for time and also had to find the projectile range with and without air resistance. this put me in an expansion parameter or coupling constant. For short, i used the "perturbation method" to come to a final answer of...

    Kinematics of pumpkin shot out of air cannon

    i'm actually starting to get somewhere now... x(t=0) = 0 = y(t=0) . x(t=0) = Vo cos theta . y(t=0) = Vo sin theta .. . mx = -kmx .. . my = -kmy - mg and I'm basically solving from there... i think i'll be okay on this question now, but any pushes while...

    Kinematics of pumpkin shot out of air cannon

    A pumpkin of mass 5kg is shot out of an air cannon at an elevation angle of 45 degrees with an initial velocity of 54m/s. It lands 142 m away. Assuming the force due to air resistance was F=-kmv, find the value of k. I need some help with this problem. I'm not quite sure how to put in the...
