    Height Ramp
Click For Summary
The discussion focuses on how the ramp angle affects the maximum height a block reaches when shot up a slope. A block is initially shot up a 40-degree frictionless slope, reaching height h, and then shot up a 20-degree slope with the same speed. Participants suggest using the conservation of energy principle, specifically kinetic energy (KE) and potential energy (PE), to determine the height without needing to calculate speed directly. The conversation emphasizes the importance of understanding energy conservation in relation to different angles. Overall, the key takeaway is that the ramp angle influences the height reached, and energy conservation can simplify the analysis.

Homework Statement


A block is shot up a frictionless 40degree slope with intial speed v. It reaches height h before sliding back down. The same block is shot with the same speed up a frictionless 20 degree slope. On this new slope, the block reaches height?


Homework Equations



1/2 mv^2 I'm not sure how to transfer this equation for speed and height when dealing with angles

Hi girlsnguitars! :smile:

You don't need speed (except that you want the height at which the speed is zero :wink:).

Just use KE + PE = constant. :smile:

Hi,
would you mind posting your answer when, or if, you get it? Thanks
 

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?
