The area of the large piston of a hydraulic lift is 40 times bigger than the area of the small piston. If the maximum force that can be applied to the small piston is 430 N, what is the maximum mass that can be lifted by the large piston?

An astronaut on the moon throws a baseball upward. the astronaut is 6 ft, 6 in. tall, and the initial velocity of the ball is 3030 ft per sec. the height s of the ball in feet is given by the equation s equals negative 2.7 t squared plus 30 t plus 6.5s=−2.7t2+30t+6.5, where t is the number of seconds after the ball was thrown. complete parts a and b.
