Climbing to New Heights: Finding Balance in Forces

How can understanding the principles of forces and tension help us solve real-life scenarios, like a mountain climber trying to remain stationary on a vertical rock face? The tension in the rope and the force exerted by the climber's feet must both equal the climber's weight (60 kg * 9.8 m/s² = 588 N) to balance the forces and keep her stationary. Therefore, the tension in the rope is 588 N, and the force exerted by her feet is also 588 N.

Understanding the concept of forces and tension is crucial when faced with scenarios where objects need to be in equilibrium or remain stationary, such as a mountain climber attempting to conquer a vertical rock face. By applying Newton's second law of motion and basic physics principles, we can calculate the forces involved to achieve balance.

Calculating the Tension in the Rope and Force Exerted with Feet

In this particular scenario, the mountain climber's weight is given as 60.0 kg. By multiplying the mass by the acceleration due to gravity (9.8 m/s²), we find that the climber's weight exerts a force of 588 N. Since the climber is stationary, the tension in the rope supporting her must also be 588 N to counteract the force of gravity pulling her downward.

Now, considering the force exerted by the climber's feet on the vertical rock face, we are told to assume negligible force exerted by her arms. This means that the force exerted with her feet should also be equal to her weight (588 N) to maintain equilibrium and prevent any motion.

Final Answer: The tension in the rope and the force exerted by the climber's feet must both be 588 N to keep her stationary on the rock face.

Explanation:

This question showcases the interplay between forces and tension in a real-life context. By recognizing that the forces must balance out for the climber to remain stationary, we can determine the necessary tension in the rope and the force exerted by the climber's feet. This application of physics principles allows us to solve practical problems and understand the dynamics at play.

To summarize, mastering the concepts of forces and tension enables us to tackle challenges like the one faced by the mountain climber, ensuring stability and safety in adventurous pursuits.
