What Equations Are Used in Projectile Motion Calculations?

AI Thread 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.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
