how much power is in my bicep if i can lift 50kg a height of 50cm 40 times in one minute?
P = F*d/t = Mg*d/t = 50*9.8 * 0.50/60s*40 = 163.3 J/s = 163.3 Watts.
power = (weight * height * reps) / time
watts = (50 * 9.8 * .5 * 40) / 60
To calculate the power in your bicep, we need to know the formula for power:
Power = Work / Time
The work can be calculated by multiplying the force (in this case, the weight lifted) by the distance traveled (height). Here, the force is 50kg and the distance is 50cm. However, we need to convert the distance to meters since the SI unit for power is watts.
1 meter = 100 centimeters
So, the distance (in meters) would be:
50cm / 100 = 0.5 meters
Now, let's calculate the work done:
Work = Force × Distance
Work = 50kg × 0.5m
Work = 25 joules
Next, to calculate the power, we also need to consider the time. You mentioned you perform this task 40 times in one minute. We'll need to convert minutes to seconds since the SI unit for power is watts.
1 minute = 60 seconds
So, the time (in seconds) would be:
1 minute × 60 = 60 seconds
Now we can calculate the power:
Power = Work / Time
Power = 25 joules / 60 seconds
Power ≈ 0.42 watts
Therefore, if you can lift 50kg a height of 50cm, 40 times in one minute, the power in your bicep would be approximately 0.42 watts.
