A 1.5 kg mass is attached to a vertically oriented spring, stretching it 0.45 m. The mass is moved upwards 0.25 m from its equilibrium position and held. A 0.8 kg mass is added to the hanging mass and the total mass is released from rest. Calculate the amplitude of the oscilating motion with both the 1.5kg and .8kg masses. Then, calculate by what total amount is the spring stretched when the speed of the masses are three-fourths the maximum speed

Forced undamped vibrations

In mechanical engineering, vibration is expressed as the term that occurs due to an object's backward and forward movement about a point of equilibrium. Generally, there are three types of vibrations which are,
