one end of a vertical spring is attached to the ground with the other end above the ground such that the spring is at its equilibrium position. the spring has negligible mass and a spring constant k0 , as shown in figure 1. when an object of mass m0 is released from rest above the spring, the object falls and then makes contact with the top of the spring with a speed v0 , as shown in figure 2. the spring then compresses such that the object reaches a position x0 below the spring’s equilibrium position, as shown in figure 3, where the object comes to rest. the object is then directed upward by the spring until it is no longer in contact with the spring. the object then continues upward. the object-spring-earth system has zero gravitational potential energy at the instant shown in figure 2. all frictional forces are considered to be negligible.

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples? ( be thorough on your answer)
