If an individual wants a work of 1300 kg m/min with a cycling speed of 300 m/min, how much resistance is needed?
To calculate the resistance needed, we can make use of the formula for work, which is given by:
Work = Force × Distance
In this case, the work required is given as 1300 kg m/min, and the cycling speed is given as 300 m/min. The cycling speed can be interpreted as the distance covered in a minute.
Since work is equal to force times distance, we can rearrange the formula to find the force:
Force = Work / Distance
Plugging in the given values, we have:
Force = 1300 kg m/min / 300 m/min
To simplify the units, we can cancel out the "min" terms:
Force = 1300 kg / 300
Now, we can calculate the force:
Force = 4.33 kg
Therefore, the resistance needed to produce a work of 1300 kg m/min with a cycling speed of 300 m/min is approximately 4.33 kg.
