Based on the conditions of the previous problem, determine the frequency and period of change of kinetic energy. 34.3. Based on the conditions of the previous problem, find the kinetic, potential and total energy of the oscillator. 34.2. A material point weighing 0.2 kg oscillates according to the law s=0.08 cos (20pi·t +pi/4). Find the speed of the point, its acceleration and the acting force, as well as the amplitude values of these quantities.
