A hоme cаre nurse is evаluаting a client whо had surgery fоr oral cancer three weeks ago. The nurse will determine the client’s long-term needs during this visit. The client is dressed, sitting at the kitchen table consuming scrambled eggs, mucous membranes are pink and moist, can only answers yes and no questions. The nurse identifies which long term goal should be continued on the client’s plan of care ?
Free respоnse questiоn 2 (Tоtаl 30 points) START ON A NEW PAGE. Work in а neаt, clean, and organized way (and get extra credit!) You'll submit your written work as a pdf after the exam is over. Briefly show your page(s) to the camera during the exam for academic integrity. Part AConsider an electric car run by a dc motor. Assuming the TF from the motor voltage V (in volts) to the car speed v (in mph) has the form . Here is some experimental information. When the car was at rest and you apply a voltage of 200Volt to the motor, the car eventually reached a speed of 40mph. The time it took to reach 98% of 40mph was 3.6 seconds. Find b and p from this information. (10 points) For consistency: Please keep all the time units in hours. Part B Here is a very simplistic model of a (rear-wheel drive) electric car run by a dc motor.The armature resistance of the motor is R, the armature inductance is about 0, the motor torque and back emf constants are both K , and the rotational inertia of the motor’s armature is 0. The total mass of the car is M and the car moves in the air with linear air drag cv . When you apply the voltage V to the motor, it provides a torque T and speed w to the input of the transmission. The transmission then delivers the torque to the rear wheels. The gear ratio of the (very light & frictionless) transmission is G . Assume the wheels too are very light and have radius r, and don’t slip on the road. Find the transfer function from the motor voltage V to the car speed v. (20 points)You’ll have to draw the the FBD of the car, and a separate FBD of the rear car wheels, and a separate for the front car wheels. Some hints: Draw FBD of the rear wheels, how much torque are they getting?Also speed of the car, assuming no slipping of the wheel, is v=rww , where ww is the angular velocity of the wheels. In going from the motor to the wheels through the transmission, while the torque increases by a factor of G (assuming no friction and massless gears), the angular velocity decreases by the same factor G . Type the final answer of Part A below.Also work on paper, show to camera during exam, and submit pdf after exam.
