Jessica and Linda, level 200 mechanical engineering students conducted an experiment to estimate the acceleration due to gravity. In the experiment, Jessica drops a ball at a distance of 1.5 metres above the floor. Linda measures the time to fall and obtains an estimate of 0.5 s. a) What do they estimate the acceleration due to gravity to be? b) Let s be the ball’s position relative to the floor. Using the value of the acceleration due to gravity that they obtained, and assuming that the ball is released at t = 0, determine s(in metres) as a function of time.
