For part b I got wrong I'm not sure how do we solve it
Fast pls solve this question correctly in 5 min pls I will give u like for sure Aka two racing boats set out from the same dock and speed away at the same constant speed of 113 km/h for half an hour (0.500 h), the blue boat headed 22.6 degrees south of west, and the green boat headed 39.8 degrees south of west. during this half hour how much farther west does the blue boat travel compared to the green boat and how much farther south does the green boat travel compared to the blue boat? express answers in km
Completely solve!Note: if you are going to use your handwriting, please write legibly because I am having a hard time understanding the handwritings of bartleby tutors recently. Thank you. 1. SpaceX rocket acceleration is expressed as a function of time given as a = bt, where b is a positive constant. (a) Find position function x(t). And (b) Find the postion and velocity at t = 5 sec. if x = 0, and v = 0 at t = 0 and b = 3 m/s3. 2. A particle travels with velocity v = (8 m/s2) t - 7 m/s. (a) Find the average acceleration for two 1-s intervals, one beginning at t = 3 s and the other beginning at t = 4 s. And (b) Sketch v versus t. (c) What is the instantaneous acceleration at any time?

I need help answering and explaning this physics FRQ: Two identical objects, A and B, move along straight, parallel, horizontal tracks. The graph attached as the image represents the position as a function of time for the two objects. (a) At approximately which time or times, if any, are the objects moving at the same speed? If the objects are never moving with the same speed during the interval shown, indicate this explicitly. Briefly explain your answer. (b) Describe what is happening to the positions of objects A and B between 3 seconds and 4 seconds. (c) Which object, if either, has an acceleration with a greater magnitude during the time interval shown in the graph? If the accelerations have the same magnitude for both objects, indicate this explicitly. (d) In a clear, coherent, paragraph-length response, explain your response to part (c). Be sure to reference and compare the graph information for both objects A and B.
