Question
![*13-100. For a short time, the 250-kg roller-coaster car with
passengers is traveling along the spiral track at a constant
speed of v= 8 m/s. If the track descends d = 12 m for every
full revolution, 0 = 27 rad, determine the magnitudes of the
components of force which the track exerts on the car in the
r.0, and z directions. Neglect the size of the car.
13-101. For a short time, the 250-kg roller-coaster car with
passengers is traveling along the spiral track at a constant
speed such that its position measured from the top of the
track has components r=10m, 0=(0.2t) rad, and z=(-0.3t) m,
where t is in seconds. Determine the magnitudes of the
components of force which the track exerts on the car in the
r, 0, and z directions at the instant t = 2 s. Neglect the size
of the car.
