The drawing shows a cylinder fitted with a piston that has a mass $$m_1$$ of $$0.480\mathrm{kg}$$ and a radius of $$2.50\times 10^2\mathrm{m}$$. The top of the piston is open to the atmosphere. The pressure beneath the piston is maintained at a reduced (but constant) value by means of the pump. As shown, a rope of negligible mass is attached to the piston and passes over two massless pulleys. The other end of the rope is attached to a block that has a mass of $$m_2=5.30\mathrm{kg}$$. The block falls from rest down through a distance of $$2.73\mathrm{m}$$ in $$1.03\mathrm{s}$$. Ignoring friction, find the absolute pressure beneath the piston. Number Units
