Assuming the girl is exerting force exactly in the same direction she is travelling in:
W=Fd or Work = Force x distance.
Force: 200N
distance: 10m
200 x 10 = 2,000 so 2,000 J (joules) of work is done... ONLY if she is exerting force in exactly the same direction she is travelling in.
-- Recall Newton's Second Law of Motion: F = (M) x (A)-- Say it in words: "The Force on a ball is equal to the mass of the ball multiplied by its acceleration."-- Look up the acceleration of gravity. It's 9.8 meters per second2 .-- Put the mass and the acceleration into the formula :F = (1) x (9.8) = 9.8 newtons .Notice that this is also the "weight" of the ball.
F = m A = (70) (9.8) = 686 newtons (154 pounds)Coincidentally, this is the same reading the skydiver sees when he steps on the bathroom scale.
Calculate this in two steps. 1. Calculate the total work required. Reminder: work = force x distance. 2. Divide the work by the time to get the power.

You can solve this in two steps. (1) Calculate the ball's volume. Use the formula for a sphere, and remember that the radius is 1/2 the diameter. Convert the result it either to cubic decimeters (= liters) or to cubic meters. (2) Divide the mass by the volume.
Obtain an appropriate weighing device. Make sure the device is calibrated properly. Perform the weighing by placing the object on top of the weighing device.
153 steps, you can get a certifcate for climbing them.

This is not a question it is a statement.
no way it makes it smaller
There are no steps to do this. You can't convert a length (yards) into an area (square meters)
Around 30 steps.

About 1500. Of course, people have steps of different lengths. Take a few of your own steps, measure how long it is, convert it to meters, then divide 1000 meters by your result.
Depends on how big your steps are and how long your legs are.
