The wood is completely immersed Suppose the ask with the wood tied to the bottom is placed on a scale. At some point the string breaks and the wood rises to the surface where it floats When the wood is floating, is the reading on the scale greater than, less than, or equal to its previous reading? O less than greater than O equal to Submit My Answers Give Up Part B Choose the best expianation from among the following: O When the block is foating the water level drops, and this reduces the reading on the scale O When the block is floating it no longer pulls upward on the flask, therefore, the reading on the scale increases The same mass is supported by the scale before and after the string breaks, and therefore the reading on the scale remains the same Subnit My Answers Give Up Proide Feodback C

Explanation / Answer

Item 9) a) w = sqrt [k/m]

= sqrt [29 / 0.5] = 7.61 rad/s

maximum speed required = A w = 3.9 * 10-2 * 7.61

vmax = 0.297 m/s

b) 1/2 k x2 + 1/2 m v2 = 1/2 k A2

(29 * x2) + (0.50 * (0.297/2)2) = (29 * 0.0392)

(29 * x2) = 0.0331

x = 3.38 cm
