A 40 kg girl runs up a flight of stairs that is 34 m high. How much work does this require?
Do you have to select a answer or write it?
work=massinKg*9.8N/kg*heightinmeters
have to write it
oh then follow what bobpursley did he's on the right track
To calculate the amount of work required, we need to use the formula:
Work = force × distance
First, we need to determine the force exerted by the girl while running up the stairs. The force is equal to the product of the mass and acceleration due to gravity.
Force = mass × acceleration due to gravity
The mass of the girl is given as 40 kg, and the acceleration due to gravity is approximately 9.8 m/s².
Force = 40 kg × 9.8 m/s² = 392 N
Now that we have the force, we can calculate the work done by multiplying it with the distance traveled. The distance is given as 34 m.
Work = Force × distance = 392 N × 34 m = 13,328 Joules
Therefore, the amount of work required for the girl to run up the flight of stairs is 13,328 Joules.
