    Undergrad Calculating Trebuchet Mechanics

    Umm, how bout lever mechanics and the angular velocity when the counterweight falls since it does not falls perfectly down and how would I convert the PE to KE, don't I have to use lever mechanics and torque since its a first class lever.

    Undergrad Calculating Trebuchet Mechanics

    Can someone please explain to me how to calculate Trebuchet mechanics? I know it involves lever mechanics with torque, angular velocity and projectile motion but I just can't seem to put these things together.

    Conservation of Energy + Projectile Motion

    lol, okay I think I know why my calculations are wrong now...my bad TYVM One more thing, so am I approaching the calculation/problem correctly? by using conservation of energy to find launch velocity and than input that into the dy=vyit+1/2ayt^2?

    Conservation of Energy + Projectile Motion

    So it lands in a hole 100cm* away in 0.05cm* deep hole.

    Conservation of Energy + Projectile Motion

    Um oh sorry about the confusion...I accidently inputed some wrong numbers, give me a second and yes that is my time

    Conservation of Energy + Projectile Motion

    Homework Statement So I have a ball rolling down a ramp structure from rest and up a curve,to launch out at 15 degrees. The ball lands 100cm away in a hole 0.05cm deep. The height in which it comes out of the ramp is 0.05cm high angle at which ball launches out = 15 degrees above horiontal...
