A person weighing 70kg runs up a flight of 30steps in 35seconds. What is the power of the person if each step is 20cm high?

A man weighing 500 N carried a load of 100 N up a flight of stairs 4 m high in 5 seconds. What is the power ?

Power required by a boy of mass 30 kg to run up a staircase of 40 steps in 10 seconds is' (Height of each step is 15 cm) (Take g = 10 m//s^(2) )

A boy of mass 40 kgruns up a flight of 50 steps,each of 10 cm high, in 5s, Find the power developed by the boy,

In an experiment to measure his power, a student records the time taken by him in running up a flight of steps on a staircase. Use the following data to calculate the power of the student : Number of steps = 28 Height of each step = 20 cm Time taken = 5.4 s Mass of student = 55 kg Acceleration = 9.8 m s^(-2) due to gravity

A man of mass 50 kg ascends 30 steps of a staircase in 15 seconds. If the height of each step of the staircase is 20 cm, find the power of the man (g=9.8 m//s^(2)).

A boy of mass 50kg, runs up a staircase of 45 steps in 10s. If the height of each step is 14cm, find his power. Take "g=10ms"^(-2)
