A car accelerates down a hill (Fig. P5.95), going from rest to 30.0 m/s in 6.00 s. A
toy inside the car hangs by a string from the car's ceiling. The ball in the figure
represents the toy, of mass 0.100 kg. The acceleration is such that the string
remains perpendicular to the ceiling. Determine (a) the angle 0 and (b) the
tension in the string.
