1. The problem statement, all variables and given/known data A 55 kg student wearing skates stands at rest on a frictionless horizontal ice surface. She throws a 10 kg backpack horizontally with a speed8.3 m/s . What is the velocity of the student after she throws the backpack? 2. Relevant equations F[tex]\Delta[/tex]t = m[tex]\Delta[/tex]v 3. The attempt at a solution so the answer should be 1.5 m/s [N] and i got this by dividing 10 kg (backpack) by 55 kg (student) and then multiplying that answer by 8.3 m/s . is this the right way or is there a proper formula i should follow? thanks !
