At 14.7 g mass is attached to a frictionless, horizontal spring. After the spring was stretched a certain distance and released, its maximum speed was found to be 4.22m/s. If the speed at x = -2.84 cm is 1.63m/s, what is the oscillation frequency of the spring?
A simple harmonic oscillator consists of a block of mass 2.2kg attached to a spring of spring constant 26N/m. When t = 1.60 s, the position and velocity of the block are x = 0.128m and v = 3.170 m/s. (a) What is the amplitude of the oscillations? ..
