What is the average power output of a weightlifter who can lift 260 kg to a height of 1.9 m in 1.8 seconds?
F = mg = 260kg * 9.8 = 2548N.
P=W/t = FD/t = 2548 * 1.9 / 1.8 = 2690.
Well, let me do some quick calculations here while juggling some numbers... Ahem! According to my clown calculations, the average power output of this weightlifter is likely equivalent to powering an entire circus tent full of bright, colorful lights! At a whopping 853.78 watts, this weightlifter could give any power plant a run for its money! So, watch out for weightlifters... they're secretly electrifying!
To find the average power output of a weightlifter, we need to use the formula:
Power = Work / Time
First, let's calculate the work done by the weightlifter.
Work = Force × Distance
The force exerted by the weightlifter can be calculated using the formula:
Force = Mass × Acceleration due to gravity
Given that the weight the lifter can lift is 260 kg, and the acceleration due to gravity is approximately 9.8 m/s^2, we can calculate the force:
Force = 260 kg × 9.8 m/s^2 = 2548 N
Next, we need to calculate the distance the weight has been lifted. The distance is given as 1.9 m.
Now, we have all the required values to calculate the work done:
Work = Force × Distance = 2548 N × 1.9 m = 4842.4 J
Finally, we can calculate the average power output using the given time:
Power = Work / Time = 4842.4 J / 1.8 s = 2690.2 W
Therefore, the average power output of the weightlifter is approximately 2690.2 Watts.
To calculate the average power output of a weightlifter, we need to use the formula:
Power = Work / Time
To find the work done by the weightlifter, we use the formula:
Work = Force x Distance
In this case, the force is equal to the weight being lifted, which is the product of the mass and the acceleration due to gravity:
Force = mass x acceleration due to gravity = 260 kg x 9.8 m/s^2
Now, to find the work done, we multiply the force by the distance lifted:
Work = Force x Distance = (260 kg x 9.8 m/s^2) x 1.9 m
Next, we divide the work done by the time taken to find the average power output:
Power = Work / Time = (260 kg x 9.8 m/s^2 x 1.9 m) / 1.8 s
Evaluating this expression, we can find the average power output of the weightlifter.
