those questions please 1. Raul is on an airplane. At one point in the flight, he measures that his luggage has an apparent weight of 155 N. The actual weight of his luggage is 128 N. Which of the following best describes the vertical motion of the airplane? The airplane is accelerating downwards at 21.7 m/s 2 The airplane is accelerating upwards at 2.07 m/s 2 The airplane is accelerating upwards at 21.7 m/s 2 The airplane is accelerating downwards at 2.07 m/s 2 2. Carrie's backpack has a mass of 7.04 1. Raul is on an airplane. At one point in the flight, he measures that his luggage has an apparent weight of 155 N. The actual weight of his luggage is 128 N. Which of the following best describes the vertical motion of the airplane? kg. What is the weight of her backpack? 69.1 N 114 N 0.718 N 7.04 N 3. During football practice, several players are pushing on a device called a tackle dummy. The device weighs 3900 N, and the normal force acting on the device is also 3900 N. Three players push the device eastward at the same time, with respective forces of 210 N, 265 N, and 244 N. The force of friction is westward with a magnitude of 240 N. What is the net force on the tackle dummy. 479 N east There is no net force acting on the tackle dummy. 959 N east 4859 N west 4. Grayson is in an elevator that is accelerating upward. Which of the following statements is accurate? His actual weight and apparent weight will both increase. His actual weight and apparent weight are equal. His apparent weight is greater than his actual weight. His apparent weight is less than his actual weight. 5. A certain car sitting at rest has two forces acting on it: the downward force of gravity, and the upward normal force. Do these two forces represent an action-reaction pair? Why or why not? . 6.Malik is pushing a cart full of equipment across the physics classroom at his school. The cart has a mass of 65.5 kg. As he pushes, the cart accelerates at a rate of 0.334 F f = F n . How much force is Malik exerting on the cart? 65.5 N 196 N 643 N 21.9 N 7. Collin places a 9.9 kg box on a 41 ramp. The box accelerates at a rate of 0.44 m/s 2 . What is the coefficient of kinetic friction between the box and the ramp? 0.81 0.54 0.77 8. Inertia is the natural tendency of every object to resist change to either speed or direction. Describe a way in which you observe this in your everyday life. 9. Two students are pushing a box along the ground, but the level of friction is making it very difficult. One of the students suggests the rotate the box so that it is sliding on its largest side, thus "spreading out the friction." Will this student's suggestion help the box slide more easily? Why or why not? 10. Aliyah is pushing a loaded shopping cart out to the car. She pushes with a force of 65.1 N, causing the cart to accelerate at a rate of 1.22 m/s . What is the mass of the loaded shopping cart? 47.6 kg 53.4 kg 65.1 kg 51.1kg
