A point moves along a circle of radius 4 cm. The distance x is related to time t by x = ct^3 , where c = 0.3 cm/s3 . Find the normal and tangential acceleration of the point at the instant when its linear velocity is v = 0.4 m/s.

Solution:
A point moves along a circle of radius 4 cm. The distance x is related to time t
