Anna walks up stairs she weighs 565n stairs go up 3.25m she climbs in 12.6 s what output?

To find the output, we can calculate the power exerted by Anna while climbing the stairs. Power is given by the formula ( P = \frac{W}{t} ), where ( W ) is the work done and ( t ) is the time taken. The work done (W) can be calculated as ( W = \text{force} \times \text{distance} = 565 , \text{N} \times 3.25 , \text{m} = 1833.75 , \text{J} ). Therefore, the power output is ( P = \frac{1833.75 , \text{J}}{12.6 , \text{s}} \approx 145.2 , \text{W} ).
