MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A student stretches a spring, attaches a 1.90 kg mass to it, and releases the mass from rest on a frictionless surface. The resulting oscillation has a period of 0.650 s and an amplitude of 30.0 cm. Determine the oscillation frequency, the spring constant, and the speed of the mass when it is halfway to the equilibrium position. HINT (a) the oscillation frequency (in Hz)...
