The drawing shows a cylinder fitted with a piston that has a mass m₁ of 0.850 kg and a radius of 2.50 x 10-2 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 m₂ = 5.30 kg.

Your answer is partially correct.
The drawing shows a cylinder fitted with a piston that has a mass m₁ of 0.850 kg and a radius of 2.50 x 10-2 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 m₂ = 5.30 kg. The block falls from rest down through a distance of 1.42 m in 2.45 s. Ignoring friction, find
the absolute pressure beneath the piston.
