Q. 1: The motion of a particle is given by a=t33t2+5, where a is the accelenation in m/s2 and t is the time in seconds. The velocity of the particle at t=1 second is 8.25m/s, and the dispiacement is 12.30 meters, Calculate the displacement and the valnoitv tar moves a distance of 120m with three phases. At first, an acceleration of 2m/s2 until the velocity of 9 is reached, afier which the velccity is constant until the cage nears the top, when the final retardation is s2. the time and the displacement of the first phase the time and the displacement of the third nhase lime taken for the car to reach the final position
