A collar with a mass of m can slide along a smooth (frictionless) shaft with angle α measured from horizontal direction. The collar is attached to a light spring with stiffness k and unstarched length a. The other end of spring is attached to a fixed point). The collar starts from rest in A when it is pulled by a force P which is constant. P is at an angle β measured from the shaft. β is constant as well. Find the speed vB of the collar in the time instant it is at point B. (Given Parameters: m, a, b , k, P, α, and β)

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current
