(b) When hitting the stationary ball for the penalty corner, Nicole hits with a stck-velocity of \( 18 \mathrm{~m} \mathrm{~s}^{-1} \). After hitting the ball, the stick continues forward at \( 12 \mathrm{~m} \mathrm{~s}^{-1} \). The mass of the stick is 600 g and the mass of the ball is 160 g . Calculate the velocity of the ball. What assumption(s) are made in your calculation?
