1. The problem statement, all variables and given/known data A machine part is undergoing SHM with a frequency of of 5hz and amplitude of 1.80cm. How long does it take the part to go from x = 0 to -1.80cm? 2. Relevant equations x = Acoswt 3. The attempt at a solution X is given and convert it to metres 0.018. I need to manipulate answer to get time. angular velocity is 2pi x 5 = 31.41. It is just an equation manipulation. could someone please show me the technique?
