Thank you so much. And it was interesting how I never thought about the anti-derivative, like what it may mean when not used appropriately, thank you.

Homework Statement The height of an object moving vertically is given by s = -16t2 + 96t + 112, when s in ft and t in sec. a. Find the object's velocity when t=0 b. Find its maximum height and when it occurs. c. Find its velocity when s=0 The Attempt at a Solution a. Now I know to find the...

Sorry, The mass of an electron is 9.1 X 10-31 After all the calculation, I get the right answer! Thanks for letting me know! I did a silly mistake!

Okay, I have made my mosetrap car, and it worked. I got the ideas and instruction off online. I am going to provide you with all the sources that I used to make my mousetrap car. http://users.bigpond.net.au/mechtoys/mouse.html http://monsterguide.net/how-to-build-a-mouse-trap-car...

Homework Statement An electron is moving through a magnetic field whose magnitude is 8.70 X 10-4 T. The electron experiances only a magnetic force and has an acceleration of magnitude 3.50 X 1014 m/s2. At a certain instant, it has a speed of 6.80 X 106 m/s. Determine the angle \theta (less...

ok, I got it. Thanks for the help guys!

Thank for replying. To find the amps through the resistor can't you just you this: V=IR 36v=I(6) I=6 Amps through the resistor. Shouldn't that be the amps going through 6 ohms resistor? After that would you find the amps going through the 8 ohms resistor? Then the answer to that would...
