What is true about the kinematics of a particle? A ) The velocity of a particle is always positive , B ) The velocity of a particle is equal to the slope of the position-time graph , C ) If the position of a particle is zero , then the velocity must zero , D ) If the velocity of a particle is zero , then its acceleration must be zero , 5:27 pm
The motion of a particle is defined by the relation x = 2t3 - 9t2 + 12t + 10 , where x and t are expressed in feet and seconds , respectively . Determine the time , the position , and the acceleration of the particle when v = 0 ? 5:08 pm
