Final position Initial position NOTE: This problem requires using two fundamental principles. We're looking down on two positions ("initial" and "final") of a spring-mass system that moves on a low-friction table, with the left end of the spring tied to the stationary black ball, which is free to turn. In the initial position the spring was relaxed, with a length of d. = 21 cm, and the sine of the angle 0, was 0.65, In the final position the length of the spring is dy= 31.5 cm is 0.44 kgm/s and the sine of the angley is 0.87. The mass of the red ball is 0.7 kg
What was the magnitude of the initial momentum? |7₁|=1 0.58 kg-m/s Hint Save for Late Using multiple attempts will impact your score. 20% score reduction after attempt 2 Part 2 What is the stiffness of the spring? stiffness k, = N/m Attempts: 1 of 3 used Submit Answer
