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

It's advisable not to blatently tell people to do your work. SageMath won't help you write down the differential equation for a given word problem (yet), you have to do that part yourself. Solving and plotting can be done, there are examples of it in the documentation. What have you tried?
