jessica and Linda, level 200 students conducted an experiment to estimate the acceleration due to gravity. in the experiment, Jessica drops a ball at a distance of 1.5metres above the floor. Linda measures the time to fall and obtains an estimate of 0.5s. 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 acceleration on due to gravity that they obtained and assuming the ball is released at t=0, determine s (in metres) as a function of time.
