In an experiment...?

Question

Is the velocity {(df -di)/(tf-ti)} of a steel and a glass sphere ball constant for a given sphere and height linear? Explain your answer. *df means finial distance, di means initial distance, tf final time and ti initial time*

Answer 1

Yes. If the balls dropped from 100m. Their acceleration would be 9.81m/s^2. Say it took 12 seconds. 100/12^2=.6944m/s. The balls would drop at a constant rate of .6944m per second.
