a horizontal force of 290N is applied to a stationary wooden box in one direction, and a 800N horizontal force is applied in the opposite direction. What additional force is needed for the box to remain stationary?
To determine the additional force needed for the box to remain stationary, we need to calculate the net force acting on the box.
The net force is the vector sum of all the applied forces. In this case, we have two horizontal forces acting in opposite directions:
Force 1: 290N (to the right)
Force 2: 800N (to the left)
Since the forces are in opposite directions, we subtract the larger force from the smaller force to determine the net force:
Net force = (Smaller force) - (Larger force)
= 290N - 800N
= -510N
The negative sign indicates that the net force is in the opposite direction of the smaller force.
Therefore, an additional force of 510N in the direction of the smaller force is needed for the box to remain stationary.
To determine the additional force needed for the box to remain stationary, we need to consider the net force acting on the box.
When two forces act in opposite directions, the net force is found by subtracting the smaller force from the larger force. In this case, the larger force is 800N, and the smaller force is 290N.
Net force = larger force - smaller force
Net force = 800N - 290N
Net force = 510N
Therefore, an additional force of 510N is needed for the box to remain stationary.
F + (800-290) = 0,
F + 510 = 0,
F = - 510N.
F should be equal and opposite of the
resultant of the other 2 forces.
