For a short time, the 550-kg roller-coaster car with passengers is traveling along the spiral track as shown in (Figure 1) at a constant speed such that its position measured from the top of the track has components r = 10 m. 0 = (0.2t) rad, and z=(-0.3t) m. where it is in seconds. Figure r= 10 m. 1 of 1 > Part A Determine the magnitudes of the components of force which the track exerts on the car in the r, 8, and a directions at the instant t 2 s. Neglect the size of the car.
