A student conducts an experiment, comparing two objects sliding down two ramps made of different materials but with the same angle. The graph below shows the total energy (potential plus kinetic) of each object over time. Which statement is most accurate?

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.
