A mass of 0.3 kg hangs motionless from a vertical spring whose length is 0.87 m and whose unstretched length is 0.47 m. Next the mass is pulled down to where the spring has a length of 1.16 m and given an initial speed upwards of 1.2 m/s. What is the maximum length of the spring during the motion that follows

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
