1. The problem statement, all variables and given/known data A rocket explodes into two fragments with the following information: Initial trajectory: 150 m/s in the x-direction, mass is 40kg Portion a, post explosion: 45 degree angle above the horizontal, 25kg Portion b, post explosion: 30 degree angle below the horizontal, 15kg 2. Relevant equations Conservation of momentum 3. The attempt at a solution pi=150(m/s)*40kg=6000 kgm/s pa=Va[cos 45, sin 45]*25kg=Va(17.68+17.68[j])kg pb=Vb(cos 30, -sin 30[j])*15kg=Vb(12.99-7.5[j])kg By conservation of momentum: pi=pa+pb Two equations in two unknowns: 17.68*Va+12.99*Vb=6000 17.68*Va-7.5*Vb=0 Solving these gives me: Va=124.2 m/s Vb=292.8 m/s However this is wrong, the answer should be: Va=43.92 m/s Vb=146.41 m/s What am I doing wrong here? This is such a simple problem I am reviewing for the EIT, but I cannot for the life of me find out whats wrong and I am getting all the other momentum problems correct. Is the solutions manual incorrect? Thank you in advance for the help!
