A man weighing 60kg lifts a body of 15kg to the top of a building 10m high in 3 minutes.The power of man is:
Question
Solution 1
To calculate the power of the man, we can use the formula:
Power = Work / Time
First, let's calculate the work done by the man. The work done is equal to the force applied multiplied by the distance moved. The force applied can be calculated using Newton's second law:
Force = mass * acceleration
