calculate the total amount of work performed in 5 minutes of exercise on the cycle ergometer given the following flywheel 25n cranking speed 60rpm distance travel 6meters
Tell me its solution
To calculate the total amount of work performed in 5 minutes of exercise on the cycle ergometer, you will need the formula for work (W).
The formula for work is:
W = Force × Distance
In this case, the force is given as 25 N (newtons) and the distance is given as 6 meters. However, we do not have the time it took to cover this distance.
To calculate the time (t) from the given cranking speed of 60rpm (revolutions per minute) and the distance traveled of 6 meters, we need to convert the cranking speed to meters per second.
To convert the cranking speed to meters per second, we can use the following formula:
Cranking speed in meters per second = Cranking speed in rpm × (2π × Radius of flywheel) / 60
The radius of the flywheel is not given, so we cannot calculate the exact value. However, let's assume a representative value of 0.5 meters for the radius.
Now, we can calculate the cranking speed in meters per second:
Cranking speed in meters per second = 60 rpm × (2π × 0.5) / 60 = π m/s
With the cranking speed in meters per second, we can calculate the time taken (t) to cover a distance of 6 meters:
Time (t) = Distance / Cranking speed in meters per second = 6 meters / π m/s
Now we have the time taken to cover the distance, we can calculate the work performed in 5 minutes (300 seconds):
Total work (W) = Force × Distance × (5 minutes / Time)
Substituting the given values:
Total work (W) = 25 N × 6 meters × (5 minutes / (6 meters / π m/s))
Simplifying this equation will give you the total amount of work performed in 5 minutes of exercise on the cycle ergometer.
