Use 3 significant digits for your answer. Use g = 10 m/s/s. An actual spring launcher uses a spring whose force constant is 800 N/m (1). The spring is enclosed and bound within a case that requires the spring to be compressed by 0.10 m (2). When loaded, the spring is compressed by another 0.20 m (3). A projectile of 0.50 kg is place on top of the spring (3). When launched, the spring goes back to the 0.10 m compression state (4). The projectile will reach some maximum height (5). 3 5

Needs Complete handwritten solution with 100 % accuracy don't use chat gpt or ai plz plz plz.

13. You learned in Science that Energy is conserved, that Potential Energy must balance Kinetic energy. Mathematically, that means: 1 mgh =-mv², where mgh is Potential %3D Energy 1 and -mv² is Kinetic energy. Reminder that m is 2 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! + tv MAR 18
