Consider a ball of mass m falling from a height of 20m without air resistance. If the height is written y(t) where t is time, use Newton’s 2nd laws to determine the differential equation for the motion of the ball. Solve the differential equation and plot the height of the ball as a function of time. Also plot the velocity of the ball as a function of time

Please solve using sage and show the codes used in the process. After the differentiate integrate the above function analytically using sage and also plot the above function from x=-1 to x= 1
