Afeather is dropped on the moon from a height of 2.0 meters. the acceleration of gravity on the moon is 1.67 m/s2 . determine the time for the feather to fall to the surface of the moon. hint: always ask yourself if you have a zero velocity which might allow you to ignore a part of the formula. round to the hundredths place (2 after the decimal), and choose the correct unit.

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
