  • forces in 2 dimensions, pulleys and tension?

    hey I need to know if I did it correctly because I got a test this week and these 2 problems are a bit challenging for me. all help will be appreciated.

    1. An object of 5.00 kilograms is found over a surface that is free of friction. This object is connected to another object of 9.00 kilograms with a light cable (not taking in account its weight) and the pulley is free of friction, The 9 kg object its not on a surface. obtain the vertical diagram of each object, the acceleration of the system and the tension of the cord.

    2. a person pulling a container at an angle of 25 degrees above the horizontal. assuming 120 kg container is moved by a tension of 420 newtons, determine a. the normal force between the ground and the container and b. acceleration of the container.

    2. There are medications that can selectively block the action of either sympathetic or parasympathetic influences on the heart. How could such medications be used to determine which of these systems is responsible for a change in heart rate such as was seen in this experiment?

    3. Compare the response and recovery times recorded in Table 1. List possible survival advantages of the differences you see.

    4. The parasympathetic and sympathetic nerve supplies are severed during heart transplantation and are not surgically repaired. Would a heart transplant recipient’s heart rate change with coughing (or with a severe fright)?

    5. You are in a remote location and a member of your party complains of chest pain and dizziness. You find that his pulse is 35 bpm. You immediately call 911 and are told that it will take 15 minutes for the helicopter to arrive. You know that CPR should not be performed on conscious individuals. Drawing from the knowledge you have gained from this experiment, what might be done to improve your patient’s pulse and blood pressure?
