A 645 g block is released from rest at height h0 above a vertical spring with spring constant k = 530 N/m and negligible mass. The block sticks to the spring and momentarily stops after compressing the spring 14.9 cm. How much work is done (a) by the block on the spring and (b) by the spring on the block? (c) What is the value of h0? (d) If the block were released from height 3h0 above the spring, what would be the maximum compression of the spring?

Potassium is a crucial element for the healthy operation of the humanbody. Potassium occurs naturally in our environment (and thus ourbodies) as three isotopes: Potassium-39, Potassium-40, and Potassium-41. Their current abundances are 93.26%, 0.012% and 6.728%. A typicalhuman body contains about 3.0 grams of Potassium per kilogram of bodymass.1. How much Potassium-40 is present in a person with a mass of 80kg?2. If, on average, the decay of Potassium-40 results in 1.10 MeV ofenergy absorbed, determine the effective dose (in Sieverts) per yeardue to Potassium-40 in an 80-kg body. Assume an RBE of 1.2. Thehalf-life of Potassium-40 is 1.28 x 10 years.
