Evaluate the efficiency of two identical-looking lifts. Lift A can raise a
5-newton weight 4 meters in 3 seconds. Lift B can raise a 10-newton
weight 3 meters in 3 seconds. The input work for each lift is 40 joules.
(1 joule = 1 newton-meter.) Fill in the missing numbers below.
Weight (newtons)
Distance (meters)
Time (seconds)
