Final position 0, 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 0.56. In the final position the length of the spring is dy = 42.0 cm. 7, is 0.41 kg-m/s, and the sine of the angle 0, is 0.87. The mass of the red ball is 0.7 kg.
Part 1 * Your answer is incorrect, What was the magnitude of the initial momentum? |P|= kg-nl/s Hint Save for Later Part 2 What is the stiffness of the spring? stiffness k eTextbook and Media Save for Later N/m Attempts: 1 of 3 used Submit Answer Attempts: 0.of 3 used Submit Answer
