If we were conducting an experiment on calculating the acceleration due to gravity by droping a stone from a specific hight and if by any suitable means, the stone was given an initial downward push instead of just being released, what effect would it have on the calculated value of "g"?

Would expect the value of acceleration (the slope) for the free falling dropped mass to be higher or lower than the acceleration due to gravity. Why? I thought lower because there was drag on the ticker tape in our experiement. Am I on the correct path??

A rocket blasts off. At 10.0 seconds after blastoff it is at 10000 feet, traveling at 3600mph . Assumin direction assuming the diection is up calculate the accceleration.

State why the acceleration due to gravity can be found using the slope of the graph.
