Car A leaves point O at t = 0 and travels a quarter circle counterclockwise at 30.0 m/s to point P. Car B will leave point O and travel to point P at the same speed but in a straight line. The radius of the circle is 100 m. At what time should car B leave point O in order to arrive at point P at the same time as car A?
1) At t = 0.
2) At t = 0.53 s.
3) At t = 4.71 s.
4) At t = 4.98 s.
5) At t = 5.24 s.
