Homework Equations
You might need to use
v^2=vi^2 + 2a(x-xi)
although I'm not really sure. :/
The Attempt at a Solution
I'm not sure how to solve this when you're not given the velocity :( I just need someone to explain how to do this, because there's 3 problems on my homework exactly like it but with different numbers. Thank you~
