Final answer:
Without the context of the hypothesis, we cannot conclusively determine if the starting height of 6 meters supports it. If the hypothesis concerns the relationship between potential energy and height, using different volumes of gasoline would affect the results. Experimental data on the time of fall and final speeds of balls in various scenarios would test the premise regarding acceleration and velocity.
Step-by-step explanation:
The lowest successful starting height of 6 meters mentioned does not provide enough context to assess whether it supports a hypothesis, as the hypothesis itself has not been stated. However, if the hypothesis was that the maximum height that can be achieved is at least 6 meters, then this evidence could potentially support it.
An experiment to understand how height varies with other factors, like the potential energy in gasoline, could be linked to the gravitational potential energy equation. Here, the volume of gasoline used to calculate the equivalent height for gravitational potential energy is significant.
If the hypothesis involves calculations based on a specific amount of energy, and gasoline is the source, then the volume chosen can affect the results because energy content is proportional to the volume of fuel.
Testing the premise that acceleration due to gravity is independent of an object's velocity by comparing the fall of different balls would require collecting data on their time of fall and final speeds to ensure that variations in initial velocity do not affect the constant acceleration due to gravity.
