5. Record the extension corresponding to each value of added mass in the tables below, you may need to hit the stop sign each time you add a new mass to prevent the masses from bouncing so you can record your measurements. Spring A: K value small = 0 . 5 Mass (g) Force (N) Extension (m) 50 0.5 N 0.901 100 1 N 1.26 250 2.5 N 2. 15 Spring B: K value large = 1 Mass (g) Force (N) Extension (m) 50 0.5 N 0.59 100 1 N 0.77 250 2.5 N 1.07 PHY 2053C Virtual Lab #3 - Work, Energy, and Power Prof. Lockwood Questions 1. Using the information you recorded in the tables above, calculate the spring constant value for each spring 2. Calculate the total potential energy stored in the spring when a 250g mass is hanging on each of the springs
