Answer аll the fоllоwing оn sepаrаte paper and upload per instructions at beginning of the test. (K = 273.15 + C) 1) A spring has an unstretched length of 12.0 cm. A 15.0 g mass is hung from the spring, stretching it to a length of 17.0 cm. a) If the mass is pulled down and released so that it oscillates, what will be the frequency of the oscillation? b) What is the period of oscillation? c) If the potential energy of the spring is 5.8 J, what is the maximum velocity of the mass? 2) A student hangs a 100.0 g bob from a string. The string is attached to a pendulum clamp and is pulled out to the side 15 degrees from equilibrium. The student measures the time it takes for the bob to move from the release point to the other side is 1.50 s. (10 pts) a) What is the length of the string? b) What would happen to the period if the bob was changed to 300.0 g? c) What kind of energy does the bob have before the student releases it? Why? d) Where is the bob have its maximum velocity? Why? 3) Some students at band camp decide to test the Doppler effect that they learned about in Physics last year. Barbie Que plays a bugle while sitting in a John Deere Gator moving toward the football field. Jim Shew student is standing on the 50 yeard line on the football field as he plays his bugle. Barbie and Jim each play a 512 Hz note on their bugles. Tim Tation, standing between them on the 25 yard line hears 5 beats/sec. What is the speed of the Gator that Barbie is riding in? Assume the temperature of the air is 27.0
