part a of the drawing shows a bucket of water suspended from the pulley of the well; the tension in the roof is 92N. part b shows the same bucket of water being pulled up from the well at a constant velocity. what is the tension in the rope in part b?
46 N
To find the tension in the rope in part b, we need to consider the forces acting on the bucket of water when it is being pulled up at a constant velocity.
When the bucket is at rest in part a, the tension in the rope is equal to the weight of the bucket, which is given as 92N.
When the bucket is pulled up at a constant velocity in part b, the forces acting on it are the tension in the rope and the weight of the bucket. Since it is moving at a constant velocity, the net force acting on it is zero.
The weight of the bucket is still the same as in part a, which is 92N. Therefore, for the net force to be zero, the tension in the rope in part b must also be 92N.
So, the tension in the rope in part b is 92N.
