3) A rocket is launched vertically. At time t=0, the rocket's engine shuts down. At that time, the rocket has reached an altitude of 450 m and is rising at a velocity of 130 m/s. Gravity then takes over. The height of the rocket as a function of time is h(t)= (-5.4/2) t^2 +130 t + 450 for t>0 (a) Create a function called height that accepts time as an input and in returns the height of the rocket. Use your function your solutions to parts b and c. (b) Plot height versus time for times from 0 to 30 seconds. Use an increment of 0.5 second in your time vector. (c) Find the time when the rocket starts to fall back to the ground. (The max function will be helpful in this exercise.)

Help me solve this USING MATLAB

3) A rocket is launched vertically. At time t=0, the
rocket's engine shuts down. At that time, the
rocket has reached an altitude of 450 m and is
rising at a velocity of 130 m/s. Gravity then takes
over. The height of the rocket as a function of time
is
h(t)= (-5.4/2) t^2 +130 t + 450 for t>0
(a) Create a function called height that accepts
time as an input and
returns the height of the rocket. Use your function
in your solutions to
parts b and c.
(b) Plot height versus time for times from 0 to 30
seconds. Use an increment
of 0.5 second in your time vector.
(c) Find the time when the rocket starts to fall back
to the ground. (The max function will be helpful in
this exercise.)

For the following concentration expressions, indicate whether they are uniform or nonuniform and in how many dimensions (OD, 1D, 2D, or 3D), and steady or unsteady. Then for the following control volume and origin, and table of constants, use Excel or Matlab to graph profiles that show how concentration changes within the control volume and over time to a limit of 20 for the following: C(x,0,0,0), C(0,y,0,0), c(0,0,z,0) and C(0,0,0,t).

Here we have a very simple one dimensional model of a stroke rehabili- tation patient supported by a robot. Often, when you have a controlled electromechanical system like a robot and a human working together, you want to separate them by a compliant mechanism (spring with stiffness k) so that the robot has some "give". Otherwise, if there are errors in the control of the robot it can be very uncomfortable for a patient. The spring has zero force when x, = xp = 0. The patient provides viscous damping with damping Xp coefficient c. Fp + C Patient mp k Xp Robot Arm Xr Figure 2: Schematic diagram of a very simplified model of a patient pushing against a robot. The robot supports the patient via a spring for safety. In this case we want to eventually determine the force that the patient is exerting on the robot as a function of time, so we'll do some steps towards that goal. Your tasks: A Draw the free body diagram for the patient mass (mass mp). B Write the equations of motion for the…

Hi, I need help on this question:a) Choose boundary conditions (b.c.) for the boundaries A-G from the types of b.c. typically implemented with an incompressible CFD solver. State what quantities those b.c. impose, and which they leave undefined. Justify your choice of boundary condition. b) Discuss the most important errors your choice of b.c. may introduce and how those could be remedied. c) While walking past your desk, your team-leader reminds you that the quantity of interest is the massflow in the lower channel, and proposes to use a slip-wall condition for B. Unfortunately she doesn’t explain her reasoning. For the next team meeting, prepare a discussion of the pros and cons of that suggestion, and explain whether or not you think this suggestion should be followed.
