The brothers of iota eta pi fraternity build a platform, supported at all four corners by vertical springs, in the basement of their frat house. a brave fraternity brother wearing a football helmet stands in the middle of the platform; his weight compresses the springs by a distance 0.19 m . then four of his fraternity brothers, pushing down at the corners of the platform, compress the springs another distance 0.52 m until the top of the brave brother's helmet is a distance 0.80m below the basement ceiling. they then simultaneously release the platform. you can ignore the masses of the springs and platform. a) when the dust clears, the fraternity asks you to calculate their fraternity brother's speed just before his helmet hit the flimsy ceiling. b) without the ceiling, how high would he have gone?

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.

Aspring has a natural length of 8 m. if a 12-n force is required to keep it stretched to a length of 10 m, how much work w is required to stretch it from 8 m to 16 m? (round your answer to two decimal places.)
