se/ViewProblem?unititemID=4124598&enrollmentID=389313 A block with mass m 7.2 kg is hung from a vertical spring. When the mass hangs in equilibrium, the spring stretches x 0.27 m. While at this equilibrium position, the mass is then given an initial push downward at v-4.8 m/s. The block oscillates on the spring without friction. 1) What is the spring constant of the spring? 261.3 3 Your submissions: 261.31 Computed value: 261.3 Feedback: Correct!

Cumulative Problem 17 A spherical container is constructed from steel and has a radius of 2.00 m at 17.0 •C. The container sits in the Sun all day, and its temperature rises to 40.0 •C. The container is initially filled completely with water, but it is not sealed. The coefficient of linear expansion of steel is 13*106. The coefficient of volume expansion of water is 207*10-6. 1) By how many cubic meters does steel expand? (Express your answer to three...
