1. Report the H and b values you measured with uncertainty. Calculate the average range you actually measured (average position of all trials), as well as its uncertainty. Report the mass of the ball with its uncertainty. Show all calculations. Explain the source of uncertainties for any values that do not require calculation.
2. Use the H and b values with uncertainty to calculate the predicted range and its uncertainty in meters. Show your work. Compare your predicted range to your measured range: are they consistent? Can you determine whether energy has been lost on the ramp? Explain.
3. Assume that the energy lost was entirely due to friction and that the total length of the PVC pipe is 1 meter. Use this length to compute the average force of friction (ignore uncertainties).

Scientists follow specific processes in order to determine valid explanations and conclusions from observations. david observed strange lights in the sky above his home outside of roswell, new mexico. the only explanation that makes sense to him is that there are ufos in the area. what should david do next to verify his explanation?
