A student walked a first displacement (D1) of 150m, 30° N of E, then walked again for a second displacement (DZ) of 230m, 60° W of N. After reaching the destination, the student walked back to the starting point in a straight-line path for the third displacement (D3). What is the magnitude and direction of (D3)?

The spring constant of the spring is 164 N/m. Assume that friction is negligble in these problems. Iam finished (A) If the mass starts from rest at a height of 1.07 cm, what is the final compression of the spring when the mass comes to rest? Assume the spring is initially uncompressed. 1.69 cm (B) If the mass initially compresses the spring 1.50 cm, what is the maximum height the mass rises to on the incline? Assume the mass is released from rest. 0.95 cm (C) If the mass is released from rest at a height of 1.07 cm, what is the compression of the spring when the mass has a speed of 33 cm/s? 1.17 cm 2:00 PM //2023Grading for Numeric Answers Tolerance Some numeric answers to questions need to be exact. For example, the answer to the question "How many days are in a week?" must be exactly 7. In general though, numeric answers are graded as correct if they fall within an acceptable range (or tolerance) of the official correct answer. For example, if the answer to a numeric problem with a tolerance of 2% was 105, then entering any value between 103 and 107 would be graded as correct, as shown in the region shaded green below. The typical grading tolerance in Mastering is 2-3%, although this value may vary (e.g. more lenient) depending on the particular problem. 100 105 Properly-rounded 110 answer +/- 2% Significant Figures While Mastering does not directly grade your answer based on the number of significant figures it contains, the tolerance mentioned above is centered around the properly-rounded answer (as opposed to the full-precision answer). In some problems you will be explicitly told how…a. which of the following would be best completed with a limit comparison test b. complete the limit comparison test on the series selected.
