The parts within the question may not have equal weight. Launcher . . h m : i \"'1 Students are going to perform an experiment to determine the launch speed 11 of a metal sphere from a launcher, using the setup shown above. They are expected to nd the launch speed '0 by plotting their data in a graph. The students have access to equipment commonly found in a high school physics laboratory, but the experiment must use the setup as shown above, which includes a metal sphere with mass on and a block of mass M2 hanging from the ceiling by light strings of negligible mass. There is a hole inside the block where the metal sphere can be captured, and additional small masses can be attached to the peg on the block, as shown. Assume that the sphere's velocity is horizontal when it collides with the block and the sphere collides with the block with its launch speed '1) (a) Briey identify each quantity to be measured, the symbol used to represent that quantity, and the equipment that would be used to measure the quantity. (b) Briey describe the procedure to be used to determine the launch speed \"0 of the sphere. Provide enough detail so that another student could replicate the experiment, including any steps necessary to reduce experimental uncertainty. As needed, use the symbols dened in part (a) above. (c) Which quantities (raw data or calculated from the data) would be graphed on the vertical and horizontal axes to produce a graph that could be used to determine the launch speed \"U of the sphere? (d) Describe which information from the graph described in part (c) would be used El how that information would be used to determine the launch speed 'U of the sphere. (e) Another group of students perform the same experiment but with longer strings of negligible mass. If the students follow the same procedure and analysis as described in part (b) through part ((1), will the magnitude of 1} that they calculate in this experiment be greater than, less than, or equal to the magnitude of '0' that the rst group of students calculated in the initial experiment?
