One end of an ideal string of length 1.50 m is fixed in space and another end is attached to a particle of mass 2.50 kg. The particle is doing circular motion in a vertical surface, as shown in Fig. 2.1. (a) If the speed of the particle at the top of its path is 7.00 m/s, what are the magnitude and direction of the tension on the particle? If the speed of the particle at point A shown in Fig. 2.1 is also 7.00 m/s, (b) what are the magnitude and direction of the tension on the particle and (c) what are the magnitude and direction of the tangential acceleration of the particle? (d) If the maximum tension that the ideal string can have is 1.20×102 N, what is the maximum speed that the particle can have at the bottom of the path without breaking the string? (e) If the same particle with the same string are doing circular motion as shown in Fig. 2.2, what is the speed of the particle? fig2.jpg

Test 2 will be offered from 11:59 pm on 6/24/2025 to 11:59 pm on 6/25/2025. Once you start the test, you have 110 minutes to finish it. Please do the following to take Test 2:Log into Blackboard with your STC credentials.Scroll down to Test 2 and click on Test 2. (You need to enable Honorlock to take the test.)You have 110 minutes to complete the Test.Test 2 will cover Chapters 4 and 5 of the textbook, i.e. the discussions in Lecture_4 and Lecture_5.You can use calculators during the test but it is a closed book test. You can use the formula sheets provided by me during the test.The test contains two parts. Part 1 is multiple choice questions and you only need to choose the correct answer for each question. Part 2 is essay questions and you need to provide the procedures to obtain your answers for the questions.For multiple choice questions (question 1 to question 10), you only need to select the correct answers.For free-response questions (question 11 to question 13), you need to show the procedures to obtain your answers. You input the procedures through the boxes below the free-response questions and it would not get full credit for solutions that only have answers but not procedures to obtain the answers.After you complete the test or before the 110 minutes are up, you make sure to submit your test. Please don’t email me your solutions for free-response questions to my email at gxu@southtexascollege.edu.It is your responsibility to make sure that you have submitted all your answers. Once you leave the test site, please don’t email me any more of your answers for the test.Do well in your studies.
