Correct Answer:
(B) Decrease the range of motion of the lift
Explanation:
Power = Work / Time.
Work = Force x Distance.
Force = Mass x Acceleration.
By decreasing the range of motion of the lift, the distance becomes smaller, thereby reducing the amount of work performed. Less work performed results in a smaller amount of power displayed.
