What is the best way to determine this? a.Use a spring scale to lift an object one meter and then to pull the same object up a ramp one meter. b. Lift an object one meter with your hands then push the same object up a ramp one meter. c. Push several objects up ramps of different heights. d. Use a spring scale to pull several objects up ramps of different heights.
