Q1. A big olive (m = 0.082 kg) lies at the origin of a xy coordinate system, and a big Brazil nut (M = 0.50 kg) lies at the point (0.92, 2.1) m. At t = 0, a force o = (3.5 + 1.6) N begins to act on the olive, and a force n = (-3.9 -3.0) N begins to act on the nut. What is (a) x and (b)y displacement of the center of mass of olive-nut system at t = 5.1 s, with respect to its position at t = 0

Q2. The G string of a guitar which should be 397 Hz is playing flat at 380 Hz. What percentage change in the tension of the wire is necessary so as to tune the string to 392 Hz?
