GP a situation. For each problem, draw a motion diagram, a force identification diagram, and a freebody diagram. A heavy box is in the back of a truck. The truck is accelerating to the right. Apply your analysis to the box.
SOLUTION: Step 1 of 4 and 2 of 4 The truck is accelerating right and heavy box is placed on the truck Step 3 of 4 Step 4 of 4 The box is not moving which is at rest but truck is moving right side and there is contact force between bottom surface of box and upper surface of truck so the static force exerts means the body tends to move or about move opposite to the direction of motion of truck and the car is accelerating towards right hence net force direction is towards right and normal force exerts vertically downward while weight acts vertically downward and opposite to the normal force.
