13. You learned in Science that Energy is conserved, that Potential Energy must balance Kinetic energy. Mathematically, that means: mgh = – nv², where mgh is Potential Energy 2 1 %3D and -mv² is Kinetic energy. Reminder that m is mass, g is the acceleration due to gravity, h is height and v is velocity. a) Balance this equation such that the sum of Potential and Kinetic Energy is zero (hint: gravity is negative). b) Solve this equation for v; again, you only need the Algebra you've learned! (hint: don't worry about the negative at the end!) Show your work!
