A dock worker pulls two boxes connected by a rope on a horizontal floor, as shown in the figure . All the ropes are horizontal,
and there is some friction with the floor.Make a free-body diagram of the box B.
2 answers:
Answer:
The worker pulls the boxes. The force (F) on box B acts towards right direction. The weigh (mg) of the box acts in the downward direction where as reaction force -Normal force (N) acts in the upward direction.
The contact surface between box and ground is not smooth and hence friction (<em>f </em>) would act in the opposite direction of the motion of the box. Tension (T) exist in the rope connecting the two boxes.
The free body diagram of box B is attached below showing all the forces acting on it.

The time period resulting in oscillations will be 1.986 seconds.
<h3>What is the period of oscillation?</h3>The period is the amount of time it takes for a particle to perform one full oscillation. T is the symbol for it. Taking the reciprocal of the frequency yields the frequency of the oscillation.
The time period of the oscillation is;
Hence the time period resulting oscillations will be 1.986 seconds.
