A 1000-kg block is held in place on an inclined wedge by a light cable on a frictionless wedge. The wedge is inclined at an angle of 37° above the horizontal and an angle of 30° is made by the cable above the surface of the wedge. Sketch a labeled free-body diagram of the box.
While going on a rescue operation, a soldier is hanging from a long rope to a helicopter, that is traveling eastward horizontally to lift people to rescue from a recent flood-affected area. If the helicopter is speeding up uniformly, then draw a clearly labeled free-body diagram for the soldier.
In a courier service office, two carton boxes, one with mass mP and the other with mass mQ, were put beside each other on a horizontal surface with zero friction coefficient. A courier boy applies a force R on box Q, so both boxes move in the same direction. Draw Free-body diagrams that are clearly labeled for both the boxes P and Q separately, indicating any pair of forces that are third-law action-reaction pairs.
A 32 kg wooden block is resting on a bench in the laboratory. A student pulls the block with an increasing horizontal force. The block moves when the pull is greater than 246 N. The student notes that the block moves with a constant velocity of 2.1 m/s when the pull is reduced to 166 N. The block-bench system is taken to Mars by an astronaut where gravitational acceleration is 3.72 m/s2. Determine how much pull will cause the block to move and its acceleration when the pull is 224 N, a force that accelerates the block at 1.8 m/s2 in the laboratory.
