A car lift is designed to raise a 14000N vehicle. The large piston area is 0.35m2 and the small piston area is 0.020m2. For safety, the applied force on the small piston must be 25% greater than the theoretical minimum. What force must the operator actually apply?
(a) 800N
(b) 1000N
(c) 640N
(d) 960N
