a quadcopter starts from the ground at the rest. It has a maximum acceleration of 2.5m/s^2 and a maximal deceleration of 3m/s^2. We want to take a picture from an altitude of 176m in a stable position. a: What is the total duration of the acceleration phase. What will be the a-t graph b. What is the maximal velocity and the v-t graph c.What is the shortest time for the quadcopter to rise to 176m. Draw the s-t graph
