Question
Chapter 3, Problem 11TE
To determine
The amount of friction force acts on the bear.
Expert Solution & Answer
Answer to Problem 11TE
The net friction force acts on the bear is .
Explanation of Solution
The bear that weighs is slides with a constant velocity and force developed by his weight initiates its movement. As the bear moves with a constant velocity, so the acceleration becomes zero.
The net force is the sum of the downward weight and the upward friction force. There is the equal and opposite amount of friction force offered by the tree to the bear by the conditions of equilibrium that help in maintaining the constant state of motion of the bear. So, the net friction force acts on the bear from the tree surface is .
Conclusion:
Therefore, the net friction force acts on the bear is .
