When a 100g mass is hung on the end of a spring, the spring extends by 2.2cm. The toy has a mass of 75g. a. What will be the elastic potential energy stored in the spring when the toy is hung up?
b. The toy is pulled down a further 2cm and then let go. How high will it rise?
c. What will be its maximum velocity and where will this occur?
d. If you joined two springs end to end, what would be the extension of the toy? What would be the new elastic potential energy?
e. If you had two springs supporting the toy side by side, how would the extension and elastic potential energy be affected?
f. Which of these two arrangements would oscillate for longer
