WE are doing this in school currently and I don't know if you know this or not, but everything is a variation of V=IR except when adding current and resistance in series/parallel. What i find that helps in this situation is to go through it step by step to figure out what's series and parallel...
Take a second and step back, then write down what each number of information represents. then see what equations use the information. Then make an attempt to solve
A 61 cm diameter wheel accelerated uniformly about its center from 120 rpm to 280 rpm in 4.0 seconds. Determine the Angular acceleration
So I converted the 120 and 280 rev per min to radians per s with 45238.93 rad/s and 105557.51 rad/s and used them as angular velocity final and initial. then...
