5. To model the motion of the child on the swing, Melissa determined that she could use the - L + . equation A\" ' \"m" (0' ) 2\"where d(t) is the distance from the child to the motion detector, in metres, and t is the time, in seconds. Use this equation to estimate when the child was moving the fastest and what speed the child was moving at this time. You are NOT allowed to use derivative. Hint: Use graphing calculator and investigate the graph
