A student runs times around a running poth at a local parkEach lapis 3 km. The student completes the first lap in 20 minutes. The student sits on a bench and rests for 5 minutes before completing the second lap in 25 minutes. Which graph best represents the student's motion

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.
