An object with mass 2.3 kg is executing simple harmonic motion, attached to a spring with spring constant 280 N/m . When the object is 0.019 m from its equilibrium position, it is moving with a speed of 0.65 m/s. Calculate the amplitude of the motion.Calculate the maximum speed attained by the object.
1 answer
from the position, calculate potential energy (1/2 k x^2), then calculate the present KE from 1/2 m v^2. Add them to get total energy. At max speed, all energy is KE, so calculate the max speed from that total energy.
