Answer:
25J
Explanation:
power = work done ÷ time taken.
and work done = force applied × distance covered.
according to the question, the athlete lifts the weight of 100N upto 5m therefore;
100N × 5m = 500N/m
then onwards,
the work done (500 N/m) should be divided by the time taken to calculate the power,
500 ÷ 20s = 25J
is your answer.
hope this helped. :)
