4. A particle is moving along a straight line through a fluid medium such that its speed is measured as v (2t) m/s, where t is in seconds. If it is released from rest at s 0 determine its positions and acceleration when t 3 s. a) s 2 m, a 9 m/s2 c) S 18 m, a 2 m/s2 d) s 2 m, a 18 m/s2 5. A driver accelerates at a rate of a(S)-0.2 S. If the driver...
