- Homework Statement
- How to solve? I don't know how to do it as mass is not given and the distance of the spring is not given either. May be impossible to solve (teacher is not the most cautious)

- Relevant Equations
- P=mv

KE = 1/2mv^2

U=1/2kx^2

1/2mv^2 = 1/2mv^2 - 1/2kx^2 but can't plug in numbers for x or m

mv+mv=mv+mv but no mass given

very lost

mv+mv=mv+mv but no mass given

very lost
