Turn on the grid
1
In the bottom tool bar, toggle the far right icon that looks like a grid.
Make a 3 by 7 rectangle
2
When you are making the rectangle it will show you the size of the square.
Make a circle with the radius of 2.25
3
When you are making the circle, it will show you the radius of the circle.
Cut the circle in half horizontally and delete the top half
4
Place the bottom half of the circle as shone
5
The top of the semicircle is aligned with the top of the rectangle.
Right click on the semicircle and go down to where it says "Combine Shapes" and select "Subtract"
6
Delete the semicircle
7
You should find a ramp underneath.
Clone the ramp three times
8
Notice that they are put side by side.
Create 3 Balls with the radius of 0.25
9
Notice the location of the balls.
Set the friction of the ramp on the far left to 0. You don't need to change the friction of the ramp in the middle and turn the friction of the ramp on the far right to +inf which will set it to infinity
