What Equations Are Used in Projectile Motion Calculations?

Click For Summary
Projectile motion calculations involve key equations that account for the effects of gravity and horizontal motion. The vertical motion is influenced by a uniform downward acceleration due to gravity, while the horizontal motion maintains a constant speed. To find quantities such as velocity and maximum height, appropriate kinematic equations should be applied separately to each component. Combining the results from both the vertical and horizontal components allows for comprehensive analysis of projectile motion. Understanding these principles is essential for solving projectile-related problems effectively.

hi,

can some one help me with projectile??its a general question..what are the equations do we use to do a sum with projectile??to find velocity??maximum height??and other stuff..
please help me as soon as possible...

For a projectile, the only force acting is gravity, which acts downward. So the vertical component of motion is characterized by having a uniform downward acceleration while the horizontal component of the motion has constant speed. Use the appropriate kinematic equations for each component and then combine them to find any quantity of interest.
 
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?
