A conveyer belt which is moving horzondally.at a speed of 4 m/s. a box of 20 kg is placed on it gently. it takes 0.1 seconds to come to rest on the belt. if the belt continues to move unifomly the distance moved by the box on the belt before settling is ?

To find the distance moved by the box on the conveyor belt before it comes to rest, we can break down the problem into a few logical steps. The key here is to understand the relationship between speed, time, and distance. Since the box is initially at rest relative to the belt, it will start moving with the speed of the belt as soon as it is placed on it. Let's go through the calculations together.

Understanding the Motion

When the box is placed on the conveyor belt, it is initially at rest. However, the belt is moving at a speed of 4 m/s. The box will start to accelerate until it matches the speed of the belt, but it takes 0.1 seconds for the box to come to rest relative to the belt. During this time, the box will move forward due to the motion of the belt.

Calculating the Distance

To find the distance the box travels on the belt while it is coming to rest, we can use the formula for distance:

  • Distance = Speed × Time

In this case, the speed of the conveyor belt is 4 m/s, and the time it takes for the box to come to rest is 0.1 seconds. Therefore, we can calculate the distance as follows:

  • Distance = 4 m/s × 0.1 s
  • Distance = 0.4 m

Final Thoughts

So, the box moves a distance of 0.4 meters on the conveyor belt before it comes to rest. This scenario illustrates how objects interact with moving surfaces and the importance of understanding relative motion. If you have any further questions about this topic or related concepts, feel free to ask!
