Ablock of mass 0.221 kg is placed on top of a light, vertical spring of force constant 5365 n/m and pushed downward so that the spring is compressed by 0.097 m. after the block is released from rest, it travels upward and then leaves the spring. to what maximum height above the point of release does it rise?

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.
