Quiz 1 DL Sec Name |___|___ Rubric Codes : last first first two letters last name I certify by my signature that I will abide by the code of academic conduct of the University of California. Signature 1 A child is bouncing on the family trampoline in the backyard such that the oscillation is small enough that the child never loses contact with the trampoline. The child’s mother is watching through the kitchen window and measures that the period of her c hild’s oscillation as 1.0 s and the amplitude as 20 cm. (a) Assuming that the motion is SHM, plot and carefully label a graph of the child’s vertical position as a function of time (over the time range 0 s to 2 s). Assume that the mother’s stopwatch starts when the child is at the equilibrium position of the child-trampoline system.

Unformatted text preview: (b) Is it possible to determine (from the information given above) the spring constant of the trampoline? If so, determine the spring constant. If not, determine what extra piece or pieces of your information you would require. Explain. (c) The child is now getting bored of jumping with such small amplitude. The child wishes to get airborne! Explain what minimum amplitude of oscillation is required to lose contact with the trampoline? Possibly useful equations and constants from Block 11: F spring k stretch ; ; ; y t B Asin 2 t ; ; ; ; ; ; ; ; y x,t B Asin 2 t T 2 x ; ; ; ....
