(I have asked for help multiple times and the answers haven't been right. Please help!)
A 0.596 kg metal cylinder is placed inside the top of a plastic tube the lower end of which is sealed off by an adjustable plunger, and comes to rest some distance above the plunger. The plastic tube has an inner radius of 6.05 mm, and is frictionless. Neither the plunger nor the metal cylinder allow any air to flow around them. If the plunger is suddenly pushed upwards, increasing the pressure between the plunger and the metal cylinder by a factor of 2.55, what is the initial acceleration of the metal cylinder? Assume the pressure outside of the tube is 1.00 atm. v=0 Number m/sExplanation / Answer
The outside pressure is 1 atm since the system was at equiliberium initially, the initial pressure inside must have been 1atm
By pushing the plunger, the pressure increases by 2.55 times becomes 2.55 atm.
now, the pressure diffrence is 2.55 -1 = 1.55 atm = 1.55*101325 = 157053.75 kg/m*s^2
Area = pi*(r)^2
= 3.14*(6.05*10^-3)^2
= 11.49*10^-5 m^2
force = pressure*area
force = 157053.75*11.49*10^-5
force = 1.810 N
acceleration = force / area
acceleration = 1.810 / 0.596
acceleration = 3.036 m/s^2.
