If the piston is moving downward at a constant velocity of 10[m/s], determine
the average pressure within the cylinder and the force required to move the
piston. Take Pair = 1.23[kg/m3], and recall that is Force times velocity,
where F = ma.

Accepted Answer

It seems like you have a physics problem involving a piston and cylinder system. The diagram shows a cylinder with an opening labeled "A" where air is drawn in, and a piston labeled "B" moving downward at a constant velocity of 10 m/s. The problem asks for the average pressure within the cylinder and the force required to move the piston, given the air density and the formula for force. Have you tried breaking down the problem step by step to see how you can apply the formula F = ma to find the force required to move the piston? Let's work through it together.
