An object of mass 10 kg and a volume of 1500 cm3 is attached to one end of a spring. The other end of the spring is attached to the bottom of a boat that is in the water. The spring constant of the spring is 2000 N/m.

 

a) Will the object float, sink, or remain stationary in the water? 

b) If the object will float or sink, determine how far the spring will be compressed or stretched respectively. 

c) Repeat parts a) and b) if the mass of the object is doubled to 20 kg, but it still has a volume of 1500 cm3.
