Ajet plane lands with a speed of 87 m/s and can accelerate at a maximum rate of −4.10 m/s2 as it comes to rest. (a) from the instant the plane touches the runway, what is the minimum time needed before it can come to rest?

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.
