A soccer ball of mass m1 = 0.57 kg is initially at rest. Another soccer ball of m2 = 0.498 kg is kicked at the first ball such that the system has an initial momentum vector of Pi = Pxi + Pyj where Px = 0.76 kg m/s and Py = 0.85 kg m/s. a) Write an expression for the initial velocity v2i for m2 in terms of the mass and the initial momentum. b) Write an expression for the final velocity v1f for m1, if v2f = v2fj. c) Numerically what is the magnitude of the final velocity v1f for m1, if v2f = 0.5j m/s?

Question
A soccer ball of mass m1 = 0.57 kg is initially at rest. Another soccer ball of m2 = 0.498 kg is kicked at the first ball such that the system has an initial momentum vector of Pi = Pxi + Pyj where Px = 0.76 kg m/s and Py = 0.85 kg m/s.
a) Write an expression for the initial velocity v2i for m2 in terms of the mass and the initial momentum.
b) Write an expression for the final velocity v1f for m1, if v2f = v2fj.
c) Numerically what is the magnitude of the final velocity v1f for m1, if v2f = 0.5j m/s?
