1. The problem statement, all variables and given/known data consider a yo-yo with R = 3.3 cm, r = 0.3 cm, and mass m = 84 g. What is the speed of the yo-yo after it has fallen a distance h = 1.20 m? What is the tension in the string while the yo-yo falls? What is the magnitude of the acceleration of the centre of mass as the yo-yo falls? 2. Relevant equations L = Iw I = 0.5MR^2 KEr = 0.5Iw^2 Tnet = Ia 3. The attempt at a solution change h into rotational displacement, not sure where to go or if thats even right. can anyone give me direction????
