A spring stretches 0.150m. when a 300.g. mass is gently lowered on it. The spring is then set up horizontally with the 300.g.mass resting on a frictionless table. The mass is pulled so that the spring stretches 0.100 m. from the equilibrium position. Determine the following: a. amplitude b. total energy of the system c. magnitude of the velocity of the mass when it is 0,050 m. from equilibrim - use energy principles d. maximum accerleraation of the mass e. period of motion f. natural frequency
