I guess I am having trouble understanding this problem. I don't even really know where to start, or what rules to use. Find the Limit: lim log10 (x2-5x+6) x->3+

The figure shows a graph of electric potential versus position along the x-axis. An proton is originally at point A, moving along in the positive x-direction. How much kinetic energy does the proton need to have at point A in order to be able to reach point E ( with no forces acting on the...

You're right. I have no idea why I didn't realize that! Thank you so much for you help.

Well, I think I'm just stuck then. Can anybody give me a clue as to what the correct amplitude shoudl be? I would really appreciate it!

Oh, okay... so then: Vmax : (2л) x (440.2Hz) x (0.00229m) = 6.33 m/s amax : [(2л x 440.2Hz)^2] x (0.00229m) = 17518 m/s2 Does that look about right? Or am I still way off?

Q: The prong of a tuning fork moves back and forth when it is set into vibration. The distance the prong moves between its extreme positions is 2.29 mm. If the frequency of the tuning fork is 440.2 Hz, what are the maximum velocity and the maximum acceleration of the prong? Assume SHM. I...

I keep getting d=.43, and I am almost positive that is not correct!

I just can't seem to derive the correct formula for this one. A spring with k=40.0 N/m is at the base of a frictionless 30 degree inclined plane. A 0.50 kg object is pressed against the spring, compressing in 0.3m from its equilibrium position. The object is then released. If the object is...

Could someone tell me what formula I should use here? A satellite travels around Earth in uniform circular motion at altitude 35836 km above Earth's surface. The satellite is in geosynchronous orbit (that is, the time for it to complete one orbit is exactly one day). In the figure below , the...

That is the right answer. I am not sure how you got that though. I guess I'll just have to keep working at it! Thanks for all your help!

I keep getting the answer 3456 N. But it keeps coming out wrong. What am I not doing correctly?

These magnitude and direction problems always give me a really hard time! What other numbers should I have in order to solve this problem? Hopefully from that I will be able to figure out the proper equation to use. Thanks! Q: A roller coaster car of mass 320 kg (including passengers)...
