    I with an AP Physics Momentum/Collision problem

    Umm for the horizontal recoil speed I used conservation of momentum: Momentum Initial = Momentum Final so 0 = mbullet*vbullet - mcannon*vcannon vcannon = mbullet*vbullet/mcannon mcannon = 4m, vbullet = vcos(θ), mbullet = m so vcannon = mvcos(θ)/4m -> vcos(θ)/4 ----------------- For the...

    I with an AP Physics Momentum/Collision problem

    AP Physics Momentum/Collision problem.. Homework Statement "A projectile of mass M is fired at an angle Theta (with the horizontal) from a cannon of mass 4M and velocity V on a friction-less flat surface. Determine Theta such that the distance from the end of the cannon (the hole of the...
