**EDIT: I solved the second part of the problem, I just need help on the syntax for the 2 equations of q(t) and I(t). Homework Statement http://img262.imageshack.us/img262/2139/phys1xf8.jpg Homework Equations First Part: q(t) = Q(1-e-t/RC) I(t) = (emf/R) e-t/RC The Attempt at a Solution...

Excuse the Title =X Homework Statement A 0.300 kg puck, initially at rest on a horizontal, frictionless surface, is struck by a 0.200 kg puck moving initially along the x-axis with a speed of 2.00 m/s. After the collision, the 0.200 kg puck has a speed of 1.00 m/s at an angle of \Theta= 50.0°...

I still need help... :(

Homework Statement A 1.00 kg object slides to the right on a surface having a coefficient of kinetic friction 0.250. The object has an initial velocity of 3.40 m/s when it makes contact with a light spring that has a force constant of 50.0 N/m. The object comes to rest after the spring has...

Homework Statement A block of mass 13.0 kg slides from rest down a frictionless 35.0° incline and is stopped by a strong spring with k = 2.60 x 10^4 N/m. The block slides 3.00 m from the point of release to the point where it comes to rest against the spring. When the block comes to rest, how...

okay i think i might've figured it out. i used the kinematic equation: V_{f}^2 = V_{i}^2 + (2ad) i assume the initial velocity is 0, so we can ignore it in this case. what I am solving for should be the final velocity. if the acceleration is pointed downwards, then a = -9.81 m/s^2? the...

im sorry guys, yeah i did make a typo and i changed plus i added the value of h[SIZE="1"]2. D H, i know i must have the wrong equation or something because i don't even know \theta. So to solve for how far the particle falls, i should use a kinematic equation instead, am i right? And Vidatu...

im sorry that doesn't really help me..

Homework Statement http://img256.imageshack.us/img256/5530/hwimgxd3.gif A particle of mass 0.450 kg is shot from P. The particle has an initial velocity V_0 with a horizontal component of 30.0 m/s. The particle rises to a maximum height of h = 21.0 m above P. Assume that h[SIZE="1"]2 =...

I'm sorry, but now I'm even more confused than before. From what you're saying, I should use the equation I gave above to calculate Fg, the magnitude of the gravitational force between the two masses. But from there I don't know how to calculate the deflection of a 40m length. Am I missing...

Well, that's what I initially thought -- the 2 masses were 1m apart attached to the cables on the ceiling. But then my textbook showed a somewhat similar example with a different diagram. It showed 1 cable hanging from a ceiling which was attached to a horizontal rod with objects of mass at...

Homework Statement A student proposes to measure the gravitational constant G by suspending two spherical objects from the ceiling of a tall cathedral and measuring the deflection of the cables from the vertical. If two 155.0 kg objects are suspended at the lower ends of cables 40.00 m long...
