Coloumbs Law & Charges. Please help! :( Homework Statement A charge of +2.0 nC and a charge of +8.0 nC are separated by 36.0 cm. Find the equilibrium position for a −2.0 nC charge as a distance from the first charge. Answer in units of cmHomework Equations q/r^2 The Attempt at a Solution I...

Okay, here is my process so far: I know that d= Vi*t + (0.5)(a)(t^2), so -8.6= -4.9t^2 t= 1.325 Then, I plugged this into the equation for the horizontal 1.2=Vi(1.325) + (-4.9)(1.325)^2 So, Vi=7.398 m/s This is where I am really stuck seeing as I was always bad at figuring out the coefficient of...

How should I determine the initial velocity of the projectile if all that is given is is the distance in x & y and the acceleration? This leaves Time, Vi & Vf unknown?

I'm really lost on how to do this physics problem because I don't really understand all the components of the problem: A 7.25 kg block is sliding at 5.45m/s on a frictionless lab bench which is 8.6m high. The block hits a 1m "rough patch" before sliding off of the lab bench, and then lands...
