The position function of a freight train is given by 30') = 371.8(1' + 1)2 with sin meters and t in seconds. At time t : 12 seconds, find the train's velocity and acceleration. O a. velocity is -0.3385 metres/second, acceleration is 0.0781 metres/(seconds squared) O b. velocity is -0.3385 metres/second, acceleration is -0.0781 metres/(seconds squared) O c. velocity is -4.4000 metres/second, acceleration is 1.0154 metres/(seconds squared) Q d. velocity is -0.0260 metres/second, acceleration is 0.0060 metres/(seconds squared) C) e. velocity is -0.4303 metres/second, acceleration is 0.1076 metres/(seconds squared) O f. velocity is 0.1692 metres/second, acceleration is 0.0130 metres/(seconds squared)
