CLICK HERE TO SEE QUESTION 2 A tоw truck pulls а cаr аlоng a gravel rоad. The force applied by the engine of the tow truck is 9 000 N. The mass of the tow truck is 1 300 kg. The mass of the car is 950 kg. The vehicles are connected to each other by an inelastic tow bar of negligible mass. See the diagram below. The tow truck and car move at a CONSTANT VELOCITY. 2.1) Define the term frictional force. (2) 2.2) NAME AND STATE the law that explains why the force exerted by the tow truck on the car is the same as the force exerted by the car on the tow truck. (3) 2.3) Draw a labelled free-body diagram indicating all the forces acting on the tow truck. (5) 2.4) If the coefficient of kinetic friction between the tow-truck tyres and the road surface is 0,45, calculate the: 2.4.1) Magnitude of the tension in the tow bar, the system is not accelerating. (5) 2.4.2) Coefficient of kinetic friction between the CAR tyres and the road surface. (5) Suddenly the tow bar between the car and the tow truck disconnects and the car comes loose. 2.5) Using a relevant law of motion, explain why the car continues moving forward for a short distance. (3) 2.6) Calculate the acceleration of the car as it comes to a stop after a short distance. (4) 2.7) A rock climber descends a cliff face by abseiling down it. The mass of the climber is 64 kg. The climber stops to rest for a moment. A photograph and a free-body diagram of the climber at rest is shown above. While the climber is stationary, the rope under tension T is at an angle of 35° to the vertical. Ignore any friction between the climber and the cliff face. 2.7.1) The climber is in equilibrium. Describe equilibrium in terms of the forces acting on the climber. (2) 2.7.2) Calculate the magnitude of the tension T in the rope while the climber is at rest. (4) 2.7.3) Hence, calculate the magnitude of the horizontal force F acting on the climber from the cliff face. (3) [36]

2. The nurse is аssisting а 79-yeаr-оld patient with infоrmatiоn about diet and weight loss. The patient has a body mass index (BMI) of 31. How should the nurse instruct this patient? Body Mass Index Standard BMI calculations are assessed for patients older than 20 years of age. Specific BMI charts are available for patients younger than 20 years. Calculation is the weight in kilograms/(height in meters)2. • Interpretations of BMI calculations are: • Less than 18.5 kg/m2 = Underweight • 18.5 kg/m2 to 24.9 kg/m2 = Normal weight • 25.0 kg/m2 to 29.9 kg/m2 = Overweight • 30.0 kg/m2 to 34.9 kg/m2 = Obese (class 1) • 35.0 kg/m2 to 39.9 kg/m2 = Obese (class 2) • More than 39.9 kg/m2 = Extreme obesity (class 3)
