simulink/matlab copy paste code

A. Create a simulation a ball thrown from 30m high up with a vertical velocity of 45m/s. Or in other words, has the following conditions: y=9.81s2my(0)=30my(0)=45sm A. Plot the output y vs, time B. Use the simulink sheleton to output correctly in your publithed pat file BONUS 5 ptsi Have your slinulation limit the ball so it cannot reach a negative height
