relevant information for problem mass of puck 175 plusminus 5 grams spring length 7cm angle of r

Question

Relevant Information for problem: mass of puck: 175 ± 5 grams; Spring length: 7 cm; angle of ramp: 21.2 degrees; total distance puck traveled at max compressed spring: 36.6 cm; change in time: 0.4 seconds. 1. What is the change in gravitational potential energy as the puck starts from the top of the ramp and maximally compresses the spring? You will have to use the tools available in the video to answer this question. Describe what values you measured, how you measured these values, and what equations you used to obtain this answer. Include a positive number if gravitational potential energy increased or a negative number if gravitational potential energy decreased. 2. Using your answer in the previous step, find the change in kinetic energy as the puck starts from the top of the ramp and maximally compresses the spring. 3. Using your answer in the previous two steps, find the change in elastic potential energy as the puck starts from the top of the ramp and maximally compresses the spring. Include a positive number if elastic potential energy increased or a negative number if elastic potential energy decreased. 4. Using conservation of energy, solve for the spring constant of the spring. Describe what values you measured, how you measured these values, and the equations used to find the spring constant.
