For a mass-spring oscillator, Newton's second law implies that the position y(t) of the mass is governed by the second-order differential equation my''(t)+by'(t)+ky(t)=0. (a) Find the equation of motion for the vibrating spring with damping if m=10 kg, b=100 kg/sec^2, k=290 kg/sec^2, y(0)=0.1 m, and y'(0)=0.1 m/sec. (b) After how many seconds will the mass in part (a) first cross the equilibrium point? (c) Find the frequency of oscillation for the spring system of part (a). (d) The corresponding undamped system has a frequency of oscillation of approximately 0.857 cycles per second. What effect does the damping have on the frequency of oscillation? What other effects does it have on the solution?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
