In a Projectile Motion Question, How to Find Theta?

AI Thread Summary
To find the angle theta in a projectile motion problem, the inverse tangent function is used, calculated as tan-1(vertical velocity/horizontal velocity). In this case, the calculation tan-1(30/7) yields an angle of approximately 77 degrees. Velocity is defined as a vector with both magnitude and direction, with vertical and horizontal components. The discussion confirms that the method for finding theta is accurate. Understanding these concepts is essential for solving projectile motion problems effectively.

Homework Statement
Excuse me for asking such a simple question, but, in a projectile motions question, if given an initial horizontal speed of 7 mps and a initial vertical speed of 30 mps how do I find theta? (the angle at launch)
Relevant Equations
I was told this was the equation for theta so: tan-1(Voy/Vox)
Solving the relevant equation tan-1(30/7) = 76.865977693604 = 77

Just need confirmation or a correction since I am very new to physics in general

Velocity is a vector with magnitude and direction. The vertical and the horizontal velocity are its components in x and y direction. To find out its angle relative to the horizontal, just divide the vertical with the horizontal and take the inverse tangent of it. Your answer is correct.

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}...

Thread 'Struggle to understand the concept of the 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...
