When the motorcyclist is at A he increases his speed along the vertical circular parth at the rate of v = (0.3t)ft/s2, where t is in seconds. If he starts from rest when he is at A, determine his velocity and acceleration when he reaches B.
[A]. v = 51.1 ft/s2, a = 9.83 ft/s2
[B]. v = 51.1 ft/s2, a = 8.18 ft/s2
[C]. v = 51.1 ft/s2, a = 10.31 ft/s2
[D]. v = 51.1 ft/s2, a = 8.69 ft/s2
