Several objects were dropped from a balcony. Use the data below to draw conclusions about the results of these drops. Be sure to: Describe the rate of speed for each object and tell when or in what order they will hit the ground with and without factoring in air resistance.
Describe the force each object will exert on the ground.
Use the data to support your conclusion statements.

i mainly need to know the rate of speed, acceleration, and force of mass

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)
