1. The problem statement, all variables and given/known data A mass of 0.5kg is suspended from a flywheel. If the mass is released from rest and falls a distance of 0.5m in 1.5s. ( mass of wheel = 3kg, Radius = 0.3m, Radius of gyration = 212mm ). Calculate : a:The linear acceleration of the mass? b: The angular acceleration of the wheel? 2. Relevant equations v=s/t a= v-u/t s=ut+1/2at^2 3. The attempt at a solution I am getting conflicting answers to these questions. Heres my attempt! v = s/t so... v = 0.5/1.5 = 0.3333ms-1. Then... a = v-u/t so... v = 0.3333 - 0/1.5 = 0.2222ms-2 So linear acceleration = 0.2222ms-2 Question b : angular acceleration = acceleration/radius. so... angular acceleration = 0.2222/ 0.3 = 0.74 Rads-2. Now my linear acceleration is 0.222ms-2 so if i put this answer into the equation s = ut + 1/2at^2. s should equal 0.5m. so.. s = 1.5+1/2X0.2222x1.5^2 = 1.75s??? The answer should be 0.5m? Any help will be greatfully accepted.
