Having aced her physics class, a student gets a cool summer job with NASA that involves playing golf on distant planets. For the first drive on the 4th hole on the planet Lgis, the total velocity of her ball is as plotted to the left. The ball lands at the same vertical level at which it starts. Along with being distant, the planet Lgis is airless, so we can ignore air resistance. 1) How far will her ball go horizontally before it strikes the ground on the first bounce? 2) What is the acceleration due to gravity on Lgis?
3) What is the maximum height the ball reaches above the surface?

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
