    nope, just gives me v1=0 and v2=0. darn.

    Projectiles physics problem - due tomorrow ;_;

    okay, this is what I've done: 1/2 m V^2 = 1/2 m 1/2 v1i ^ 2 + 1/2 m 1/2 v2i ^ 2 which equates to V^2 = v1i^2 + v2i^2 / 4mV = mv1/2 + mv2/2 which equates to V = (v1+v2)/2 V^2 = (v1^2 + 2v1v2 + v2^2)/4 ... which doesent directly equal v1i^2 + v2i^2 / 4 ... neat. let me see if i just accidentally...

    Projectiles physics problem - due tomorrow ;_;

    oh, forgot to say, this is the third part - i already found Delta K / K initial and solved some change-in-K relative to Theta equations. The problem is, if i sub kinetic energy = kinetic energy into conservation of momentum, i get V = V. Can i somehow use my Delta K/K equation here? I am...

    Projectiles physics problem - due tomorrow ;_;

    hey everybody, i would really appreciate a little help with this. I have a projectile, labeled zero, with mass m and velocity V. it travels in a parabolic motion until it reaches its apex, at which point it divides into two equal pieces, 1 and 2, with mass m/2 and m/2. Each of these pieces...
