Given,
Work done = 350 Joules
Power = 125 Watt
To find,
Time taken
Solution,
The time taken by the runner to do the work of 350 Joules and to make 125 Watt power is 2.8 sec.
We can simply find the time taken by the runner by using the formula
Power = work done / time
Time = Work done / power
= 350/125
= 14/5
= 2.8 sec
Hence, the time taken by the runner to do the work of 350 Joules and to make 125 Watt power is 2.8 sec.
