The drawing below shows a hydraulic chamber in which a spring (spring constant = 1580 N/m) is attached to the input piston (A1 = 15.0 cm2), and a rock of mass 37.8 kg rests on the output plunger (A2 = 62.8 cm2). The piston and plunger are nearly at the same height, and each has a negligible mass. By how much is the spring compressed from its unstrained position? - convert A1 and A2 to meters^2 (move decimal 4 left) kx/A1 = mg/A2 solve for x A recreational (open) hot air balloon (i.e., Pi...
