Answer:
Efficiency: 0.4 (40%)
Explanation:
The efficiency of a simple machine is given by the ratio
where
is the input work of the machine
is the output work of the machine
For the machine in this problem, we have:
is the output work
is the input work
Therefore, the efficiency of the machine is
Which can be also written as percentage:
