Think of the mass hanging from the spring in Q2. If one pulls the mass down by 'y' amount and lets go, how far up past the equilibrium point does the mass go before coming to a stop?

In a series RCL circuit the generator is set to a frequency that is not the resonant frequency. This nonresonant frequency is such that the ratio of the inductive reactance to the capacitive reactance of the circuit is observed to be 4.91. The resonant frequency is 240 Hz. ...

A ball of mass 0.1 kg is attached to a rubber band, which we can model as a spring of stiffness 8 N/m. With one end of the rubber band fixed, you throw the ball vertically upward with an initial speed of 14 m/s. At the moment the ball leaves your hand, the rubber band is ...

The spring in the muzzle of a child's spring gun has a spring constant of 780 N/m. To shoot a ball from the gun, first the spring is compressed and then the ball is placed on it. The gun's trigger then releases the spring, which pushes the ball through the muzzle. The ball ...

If a mass attached to the center of a vertical circle swings around at a fixed speed (v) and gravity pulls straight downward, would the tensions in the rope attached to the mass be different at the top of the circle, straight down to bottom of circle, and directly straight out...

A 0.200-m uniform bar has a mass of 0.750 kg and is released from rest in the vertical position, as the drawing indicates. The spring is initially unstrained and has a spring constant of k = 25.0 N/m. Find the tangential speed with which end A strikes the horizontal surface.
