after an ice show, Michelle helps clear the props from the ice. Standing in her skates next to a potted artifical tree, she gives it a push. The tree, which has a mass of 6500g, slides forward at a velocity of 13m/s. Michelle, with a mass of 40.0kg, slides in the opposite direction. What is Michelle's velocity after pushing the tree?

0= m1•v1- m2•v2
v2 =m1•v1/m2 =6.5•13/40 =2.11 m/s
