Question

A student must find the total mass of several bouncing balls, but none of the balls will remain on the triple beam balance. Propose a method for measuring the mass of the bouncing balls using the balance. Describe the tools, methods, and data table the student would need to create in order to determine the mass of the balls.

Answer 1

you should try this...
if the balls are bouncing, they will transfer a force to the scale making it show more than the ball weighs. If you break it down in pieces, taking each bouncing ball at a time, you'd have to measure each ball's acceleration, and volume. From the ball's top point, you can start timing it until it reaches the buttom, that's the acceleration, you can use a light bulb on one side and a milimetric paper on the opposite to find out the diameter of the sphere without stopping it, and you'd need the specific weight, for a chromium steel ball baring it would be around 7-7,5 grams per cubic centimeter.From here on you'd have to measure the force it implements to the scale and transform it from mass to velocity
that's done with this: spped multiplied by mass equals force
V*m=L
you'd need a few more basic physics equations, and it's pretty much straight forward...
