what are you asked to solve? The magnetic field at the dot?

You have the right idea. Two separate equations and solve them. Go with it.

Remember, average speed is distance/time.

Algebra. If your algebra is good, you will do well in calculus.

You have been doing a lot with fibonacci lately, haven't you aisha? This is another example.

Why don't you start by figuring out what happens to a projectile at its max heights and then find a mathematical relationship for that. Then do the same for the range, and see what you can come up with.

Gravity always works in one direction: downwards.

Well if you have to solve it using determinants then you probably need to solve it using Cramer's rule.

The spring is whirled in a horizontal circle. It is in uniform circular motion. Use that to compare the forces acting on the two springs in either situation.

You would take tim's time minus rick's time since tim takes less time. After that it is just algebra. All you have to do is simplify it.

Now that's better, youre right, it doesn't have to be between the two. Now which side would it have to be on?

Yes, exactly. If the charge is placed in between the two particles, it will be repelled by one and attracted by the other. Therefore, both of the two particles will force it in the same direction. If that is true, how is it possible for the forces to cancel out? I don't believe either of the...

If you multiply the first equation by sqrt(3), you will see that the two become identical. This means that they are linearly dependent and there will be NO unique solution. There will actually be an infinite number of solutions. Maybe that is what your prof was trying to show.

if the electric field at point r is zero than a point charge placed at point r will experience no force. Now, if we look at your problem. Suppose we place a negative charge somewhere in between the two particles. How will it interract with the other two? (Pay close attention to the direction of...

Does your data logger measure the motion of the spring system? If it does than when you graph it you should see the periodic motion with the damping involved. It will look sort of like a funnel. If you have good programming skills, you could take the data set that you get from the data...
