Elastic Potential Energy Ep = ½ kx2 You must show the formula(s) and solution documentation for each problem. 1. A spring gun is loaded with a bullet that has a mass of 0.01 kg. The spring compresses a distance of 0.3 m. The spring constant is 14 N/m. What is the elastic potential energy of the spring?
2. A bowling ball drops straight down on a mattress with a spring constant of 5 N/m. The mattress compresses a distance of 0.07 m. What is the elastic potential energy in the mattress?
3. Garland rides on a pogo stick. He compresses down a distance of 0.6 m. The spring constant for the pogo stick is 23 N/m. What is the elastic potential energy of Garland on the pogo stick?
4. A car that cannot stop slams into a crash cushioning system. The spring constant on the system is 50 N/m. The system is 10 meters long. What energy can the system absorb?
5. The pullback starter on a pinball machine has a spring constant of 24 N/m. How much energy will the ball have if it is pulled back a distance of 0.1 m?
6. To compress spring 1 by 0.20 m takes 150 J of energy. Stretching spring 2 by 0.30 m requires 210 J of energy. Which spring has the higher spring constant value?
7. A compressed spring that obeys Hooke's law has a potential energy of 18 J. If the spring constant of the spring is 400 N/m, find the distance by which the spring is compressed.
8. A spring gun is loaded with a bullet that has a mass of 0.02 kg. The spring compresses a distance of 0.2 m. The spring constant is 51 N/m. a. How much elastic potential energy does the bullet have?
b. If all the elastic potential energy is converted to KE, what is the KE of the bullet?
c. How fast will the bullet be going when it comes out?
