Create a Simulink model for the problem pictured below, but note that the rate of change of the height should be negative because as time increases, the height (y) decreases. 2. Define y0,g, and rh in the Matlab workspace. 3. The sqrt and square functions are located in the Math Function block that can be found in the Math Operations Library of Simulink. 4. Display the value of y in an oscilloscope from 0 to 3000 seconds. Use your oscilloscope image to determine the time to the nearest second that y reaches 0.1m. Print this value in your title block of your model. You can use zoom with the oscilloscope image to improve your estimate. 10.6 Problems 311 21. A water tank shaped as an inverted frustum cone has a circular hole at the bottom on the side, as shown. According to Torricelli's law, the speed v of the water that is discharging from the hole is given by: v=2gh where h is the height of the water and g=9.81m/s2. The rate at which the height, y, of the water in the tank changes as the water flows out through the hole is given by: dtdy=(20.5y)22gyrh2ofchange. where rh is the radius of the hole. Solve the differential equation for y. The initial height of the water is y=2m. Solve the problem for different times and find the time where y=0.1m. Make a plot of y as a function of time
