Calculation of Power of the Student
To calculate the power of the student, we need to use the formula:
Power = Work done / Time taken
To calculate the work done by the student, we need to find the gravitational potential energy he gained by climbing the steps. The formula for gravitational potential energy is:
Gravitational potential energy = Mass x Gravity x Height
Given:
Number of steps = 28
Height of each step = 20 cm = 0.2 m
Mass of student = 55 kg
Acceleration due to gravity = 9.8 m/s²
Time taken = 5.4 seconds
1. Calculation of Height Climbed
Total height climbed by the student can be calculated as:
Height climbed = 28 x 0.2 m = 5.6 m
2. Calculation of Work Done
The work done by the student is equal to the gravitational potential energy gained by him, which can be calculated as:
Work done = Gravitational potential energy = Mass x Gravity x Height
Work done = 55 kg x 9.8 m/s² x 5.6 m = 3058.4 J
3. Calculation of Power
The power of the student can be calculated as:
Power = Work done / Time taken
Power = 3058.4 J / 5.4 s = 566.07 W
Therefore, the power of the student is 566.07 W (approx. 559 W).
Conclusion
The power of the student can be calculated by finding the work done by him and dividing it by the time taken. The work done can be calculated by finding the gravitational potential energy gained by the student, which can be calculated using the mass, gravity, and height climbed.
