Projectile motion -

  1. Dec 9, 2006 #1
    projectile motion --plz help :(

    1. The problem statement, all variables and given/known data

    you have a spring launcher and it can shoot springs at angles that you can alter, but you need to find the velocity at the given angle. the velocity you need to find is like muzzle velocity. you're supposed to stretch the spring and it needs to be shot vertically into the air.
    also the launch height isnt necessarily the same as when it lands. how would u find this velocity thru experimentation?!
    2. Relevant equations

    kinematics equations

    3. The attempt at a solution

    plzzz help

    Use a stopwatch to determine the time till it lands on the ground.
