Acar weighing 15,000 n is on a hydraulic lift platform measuring 10 m2
. what is the area of the smaller piston if a force of 1,100 n is used to lift the car?

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)
