the question, from the Nelson Physics 12 texbook, is : Three charges are placed at the corners of an equilateral triangle with sides of length 2.0 m. the charges, in clockwise starting at the top of the triangle are (c being coulombs) +4.0^-6 c, +2.0^-6 c, and -4.0^-6 c. a) calculate the...

yup... figured that.

the time displacement between each track (recording of position of puck) is 30 ms...if that helps...

mmmhmmm... thought so. but to find the angle of the table you would use the height of the table + book and the lenght, then the heigh from the table to the airtable top?

the lab involves an air hockey tab set up on a slight angle (one side is raised by a textbook) and the puck is pushed in such a way as to create what looks like a parabolic shape on the paper with carbon markings. The point is to determine if the motion is a projectile motion. So far, my group...
