if you exert a force of 500 N to walk 4 m up a flight of stairs in 4 s, how much
How much what? How much power is needed?
(Force)*(Distance)/Time = 500 W
To find the work done, we can use the formula:
Work = Force * Distance * Cos(theta)
Where:
- Work is the amount of work done in Joules (J)
- Force is the applied force in Newtons (N)
- Distance is the displacement in meters (m)
- theta is the angle between the applied force and the displacement (in this case, theta is 0 degrees since the force and displacement are in the same direction)
Given:
- Force = 500 N
- Distance = 4 m
- theta = 0 degrees
By substituting the given values into the formula, we can calculate the work done:
Work = 500 N * 4 m * Cos(0 degrees)
Work = 500 N * 4 m * 1 (Cosine of 0 degrees is 1)
Work = 2000 J
Therefore, the work done to walk up the flight of stairs is 2000 Joules.
