• Con of momentum: Initial momentum = final momentum M1*v1i + m2*v2i = 0 V1i = -m2/m1*v2i I'll set m1 = 1 kg, m2 = 2 kg V1i = -2*v2i Ratio = KE1i/KE2i Ratio = (1/2*m1*v1i^2)/(1/2*m2*v2i^2) With m1 and m2 subbed in Ratio = 1/2*v1i^2/v2i^…

• Equation of motion in the vertical direction: hf = hi + vi*t - 1/2*g*t^2 Stone 1: hi = 0 vi = 50 m/s hf = 50*t - 4.905*t^2 Stone 2: hi = 100 m vi = 0 hf = 100 - 4.905*t^2 Set equal and solve for 't' 100 - 4.905*t^2 = 50*t - 4.90…
