Answer:
The efficiency of the system is 89.3%
Explanation:
Efficiency of a machine is defined as the ratio of useful work done by a machine to the total work put into the machine.
Mathematically, efficiency = (work output/work input) * 100%
work output = load * load distance
where load = 100 kg * 10 m/s² = 1000 N; load distance = 6m
work output = 1000 * 6 = 6000 J
work input = effort * effort distance
where effort = 280 N, effort distance = 24 m
work input = 280 * 24 = 6720 J
Efficiency = (6000/6720) * 100%
Efficiency = 89.3%
Therefore, the efficiency of the system is 89.3%
