You are deep in outer space (far from any gravitational sources) and standing at the center of a rotating platform (it lies in the plane z=0, and rotates ccw with angular velocity 2). you look down and see a puck on the platform with coordinates (x, y) (in your, the tt, frame). a) write down newton's 2nd law for the x & y coordinates of the puck as you observe it (2 eqs) b) write down the general solution to these two equations by changing to complex coordinates (i. e. write n = x + iy) and guessing that one of the solutions has the form n = e-iat (what is the form of the second solution, when you have two solutions which have the same form? this arose in taylor's discussion of the critically damped oscillator in section 5.4) c) at time t=0 the puck is launced from position to = (x0,0) with velocity v = (vxo, vyo) (all in your frame). show that the time dependent coordinates obey: x(t) = (xo + vxot) cos(at) + (vyo + nx)t sin(nt) y(t) = -(xo + vxot) sin(t) + (vvo + 1x)t cos(at)

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?
