... 11. On a windless day an airplane travels with a speed of 900 km/h with respect to the air at an altitude of 7.00 km. The pilot then has the airplane climb at an angle of 35.0 degrees to the horizontal while maintaining the same constant speed. The pilot releases a package when the plane reaches an ...

... 1. * (a) If an object is at rest, can you conclude that no external forces are acting on it? (b) Is it possible for an object to be moving if no net force is acting on it? Explain both in terms of the Law of Inertia and give an example. 2. A box rests on the (frictionless) bed of a truck. The truck ...

... 1. Identify all forces acting on the object -Pushes or Pulls -Frictional forces -Tension in a string -Gravitational Force (or weight = mg where g is 9.8 m/s2) - “Normal forces” (one object touching another). 2. Draw a “Freebody Diagram” -draw the object, show all forces acting on that object as vect ...

... Solution The pivot point is at the hinges of the door, opposite to where you were pushing the door. The force you used was 50N, at a distance 1.0m from the pivot point. You hit the door perpendicular to its plane, so the angle between the door and the direction of force was 90 degrees. Since = r x ...
