II. Direction: Indicate whether each of the following statements is TRUE or FALSE. If the statement is false, explain why! 1. We can approximate the study of motion on a frictionless surface by making the surface that we are studying smoother. 2. A net force is needed to maintain a body at constant speed. _3. A body at rest is free from any influence or force. 4. Newton's first law of motion is valid on all kinds of frames of reference. 5. All inertial frames moving with constant velocity relative to an inertial frame are also inertial frames of reference. 6. The direction of acceleration of a body is the same as the direction of the force acting on the body. 7. The same force on objects of different masses will yield different accelerations of these objects. 8. The acceleration of a body is inversely proportional to its mass and directly proportional to the resultant external force acting on it. 9. The first law of motion is a special case of the second law of motion. 10. If the resultant force of a body is zero, the acceleration of the body is zero. Therefore, in the absence of an applied force, a body will move with constant velocity or be at rest. 11. When a body exerts a force on a second body, the second body will exert a force on the first body. 12. When you push a wall, the wall will also push you with a force that is lesser in magnitude. 13. The force applied by a person on an object is always the "action" and the force exerted by the object on the person, the "reaction." 14. The direction of the action and reaction forces are always opposite. 15. The action and reaction forces are exerted on different bodies.Solve the following problems. Draw the freebody diagram. provide the given. required. and show solutions. 1. Sophia exerts a steady 40H horizontal force on an 8kg box resting on a tab bench. The box slides against a horizontal friction force of 24 N. Show that the box accelerates at 2 rnfs 2 . 2. A business jet of mass 30.000 kg takes off when the thrust for each of two engines is 30.000 N. Show that its acceleration is 2 m/s. 3. A rocket of mass 100.000 kg undergoes an acceleration of 2 mfs 2. Show that the net force acting on it is 200,000 N
