The position vs. time graph below is for an object that is exhibiting SHM. The position function is: x(t) = Acos(at+D). Use this graph to fill in the table. x (m) AA 10 15 20 25 20 25 30 35 40 25 -25 -50- A (m) (s) t(s) f (Hz) Vmax (m/s) Part 2: Block on a horizontal surface A 20 kg block on a horizontal surface is attached to a 434 N/m spring. The block is exhibiting SHM and has a total energy of 7435 J. The surface is frictionless. Determine the amplitude and the max speed. A 5.85m Vmax 27.26m/s Part 3: Finding vi A simple harmonic oscillator (SHO) with a mass of 62 kg has a total energy of 1017 J. Determine how fast the SHO is moving when its potential energy is 8 times its kinetic energy. Express your answer using appropriate mks. units. v= 6.6 m/s
