Below is the work I completed for Unit 2 Video Assignment: Spring Propelled Projectile. Is there anyone that can verify my work? The video data is also attached if you need it.

\fKid = mgh2 (0. 0163)-9. 8 .(0. 75)-2 = (0. 057 = 73. 74 # 73.7 N/Kad- = mgha (0. 0163)-9. 8 (1. 2)-2 Ka = (0. 072)- = 73. 953 ~ 73.9 N/mReview how to calculate Gravitational Potential Energy. PEER,\" = weight I l.II'erh'ml displacement = W11 = mgh You will use 9' = 9.8%. You are using 11 for vertical displacement since if is used for the displacement of the spring
