Question
How much power does she expend when cycling at that speed?A. $100 \mathrm{W}$B. $200 \mathrm{W}$C. $400 \mathrm{W}$D. $1000 \mathrm{W}$
Step 1
Work is given by the formula: Work = Force Ă— Distance The force exerted by the cyclist is given as 200 N. The distance covered in 1 minute at a speed of 20 m/s can be calculated as follows: Distance = Speed Ă— Time Distance = 20 m/s Ă— 60 s = 1200 m Now, we can Show more…
