1. The problem statement, all variables and given/known data The 30-kg reel is mounted on the 20-kg cart. If the cable wrapped around the inner hub of the reel, with radius 150mm, is subjected to a force of P=50 N, determine the velocity of the cart and the angular velocity of the reel when t=4 sec . The radius of gyration of the reel about its center of mass O is kO = 250 mm. Neglect the size of the small wheels. Attached is a picture 2. Relevant equations IG*ω1+Σ [itex]\int[/itex]MGdt=IG*ω2 3. The attempt at a solution I=mk2=1.875 kg/m2 So my impulse equation solves down to: P*r*t=Iω2+mv2 I end up with 2 variables and 1 equation. What is my missing equation, or how do I relate ω2 and v2?
