1. The problem statement, all variables and given/known data the turntable is rotating at 36.25 rpm. the simple pendulum is performing SHM at 36.00 prm. how many complete oscillations would the pendulum execute so that both are in phase? 2. Relevant equations 3. The attempt at a solution my working is 36prm divided by 0.25 rpm =144 oscillations. i just 'simply' work out the answer. and the answer is same with the sample answer coincidently. but i dont understand it. can someone explain please?
