Find the final velocities of (a) the 1.70-kg ball and of (b) the 9.60-kg ball if the collision is elastic. (c) Find the magnitude and direction of the final velocity of the two balls if the collision is completely inelastic.

a)
here
elastic collision:
v1' = 2(m1 * v1 + m2 * v2)/(m1 + m2) - v1
v1' = 2(1.7 * 1.85 + 9.6 * 0) / (11.3) - 1.7 = - 1.14 m/s
b)
v2' = 2(m1 * v1 + m2 * v2)/(m1 + m2) - v2
v2' = 2(1.7 * 1.85 + 9.6 * 0)/(11.3) - 0
v2' = 0.556 m/s
c)
v' = (v1 * m1 + v2 * m2) / (m1+m2)
v' = (1.7 * 1.85 )/(11.3) = 0.278 m/s
