Final Position Mmmmwwwwww D 0 Initial Position Note This Problem Requires Using Two Fundamental Principles We Re Loo 1 (56.04 KiB) Viewed 31 times

Part 1: What was the magnitude |p→i| of
the initial momentum?
Part 2: What is the stiffness of the
spring?
Final position mmmmwwwwww d₁ 0₁ 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; = 28 cm, and the sine of the angle 0; was 0.50. In the final position the length of the spring is df = 42.0 cm, P is 0.31 kg-m/s, and the sine of the angle 0, is 0.85. The mass of the red ball is 0.7 kg. Part 1 What was the magnitude of the initial momentum?
