Alright, I ended up remembering how to do these problems.

Hey, It's been about 2 weeks since I've had a physics class and I just can't seem to put things together again. I have two problems that seem like they should be easy, and I'm sure they are, but am unsure on how to do them. A constant force of 6.00N acts on a 3.00-kg object for 10.0 s. What...

ok, thanks for the help, I appreciate it much.

angular acceleration= 1.2 rad/s^2

So: Tnet = (9.8 x 3.1)(1.2)-(9.8 x 2.3)(1.2)= 9.408? What's next? \tau = I \alpha \ 9.408=7.776\alpha ??

so \tau_\textit{net} = FR_1 + FR_2 was not right?

so Tnet = (9.8 x 2.3)(1.2)+(9.8 x 3.1)(1.2)? Tnet=F(m*a)R1+F(m*a)R2?

The problem doesn't state the mass of the rod, just the masses on both ends. How do i find the torque if I've only got the inertia?

I=(2.3)(1.2)^2= 3.312 I=(3.1)(1.2)^2= 4.464 3.312+4.464= 7.776. = I.. is this right so far?

A rod of length 2.4 m is pivoted at its center and masses of 2.3 kg and 3.1 kg are hung from its two ends. Find the initial angular acceleration of the rod when the system is released from a starting position of the rod that is horizontal. The radius of the rod would be r=1/2(2.4).. which is...

wow, thanks. That should help me greatly.

A car wheel turns through 277 degrees in 10.7 s. Calculate the angular speed of the wheel. Well, i know the Angular Accelereartion is equal to the change in angular velocity divided by the time required to make that change. So should i first convert 277 degrees to radians?.. which is...
