B1. (a) A particle is moving alone a straight line such that its speed is defined as v= (-4.s2) m/s, where s is in meters. If s = 2 m when t=0, determine the velocity and acceleration as functions of time. (6 marks) (b) A bowling ball is cast on the “alley” with a backspin of w= 10 rad/s while its center O has a forward velocity of vo = 8 m/s. Determine the velocity of the contact point A in contact with the alley.
