1. The problem statement, all variables and given/known data I am given the location of 3 points in space: Z1= 3+3i Z2= 7+5i Z3= 5+5i and the velocity of two points: V_1= 8+0i V_2= 7+6i How do I find V3? 2. Relevant equations V_1/2= V_1-V_2 V_3= V1+V_3/1 V_2/1= V_2-V_1 3. The attempt at a solution I have the equations, but I just can't seem to figure out how to relate V_3 with V_2 and V_1. Can anyone help?
