How do I calculate the maximum height of a pendulum swing?

Click For Summary
To calculate the maximum height of a pendulum swing, one must consider the forces acting on the mass, including tension and gravitational force. The tension at the lowest point is 20N, which can be used to determine the net force and acceleration of the mass. Applying the principles of energy conservation, the kinetic energy at the lowest point converts to potential energy at the maximum height. A free body diagram (FBD) can help visualize the forces and clarify the relationship between them. Understanding these concepts is crucial for solving the problem effectively.

Homework Statement


A pendulum consists of a 1.5kg mass swinging at the end of a string of length 2.0m. At the lowest point in the swing the tension in the string is equal to 20N. To what maximum height above this lowest point will the mass rise during its oscillation?


Homework Equations


I'm not sure.

Start with the relevant equations. What is the equation that relates the force on an object that is in uniform circular motion? What is different about a pendulum -- what extra force(s) are in play?

Draw a free body diagram (FBD) for the mass at the bottom part of the swing...
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
