Now please atleast answer this question

For a short time, the 400-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
t 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, 0, and z directions at the instant t = 2 s. Neglect the size of the car.
Express your answers in newtons using three significant figures separated by commas.
