A group of physics students performed an experiment to verify how the distance covered by a ball projected by their Projectile Launcher varies with time. Results of the experiment are provided below. Time (t) in seconds Distance (y) in cm 0 1 | 2 | 3 | 4 | 5 6 | 7 | 8 0 15 20 | 15 | 0 |-25 |-60| -105 | -160 (a) What method can be used to find the variation of distance with respect to time? How will this method be used to carry out the purpose of the experiment? Discuss explicitly the different steps involved. (b) What is the linearized equation? What is the relationship between the distance covered by the projectile and the time of travel?
