How Do You Calculate Acceleration with Different Units of Force and Mass?

Click For Summary
To calculate acceleration when mass is given in pounds and force in dynes, the equation F = ma should be used, where F is force, m is mass, and a is acceleration. The mass of 32 lb needs to be converted to kilograms, and the force of 10 dynes should be converted to Newtons for consistent units. The conversions are necessary to apply the equation correctly. The discussion also briefly mentions a historical reference to David and Goliath, but it does not pertain to the calculation topic. Accurate unit conversion is essential for solving the problem effectively.

if the mass is 32 lb and the force is 10dyn what is the acceleration??


Homework Equations



a=f.m i don't know if this equation is right...

No, the equation is F = m a. It should be in your textbook or class notes.

Most likely, you would convert mass into kg and force into Newtons.
 
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?
