Soccer ball question: hypotenuse/adjacent and opposite lengths

AI Thread Summary
To find the vertical and horizontal components of the soccer ball's velocity vector, use trigonometric functions based on the 45-degree angle. The vertical component can be calculated as 30 m/s multiplied by the sine of 45 degrees, while the horizontal component is found using the cosine of 45 degrees. Both components will equal approximately 21.21 m/s since sine and cosine of 45 degrees are equal. Creating a diagram helps visualize the problem, and applying basic trigonometry will clarify the solution. Understanding these concepts is essential for solving similar physics problems in the future.

Jake kicked a soccer ball into the air at an angle of 45 degrees to the horizontal with an intial result velocity of 30 m/s. Find both the vertical and horizzonatal components of the velocity vector. Hint: the angle of your interest is 45 degrees and you want to find adjacent and opposite lengths with the given hypotenuse 30 m/s.

Thanks for any help provided.

The question pretty much says everything...
 
But I know nothing :(
 
draw a diagram, label the hypotenuse as your velocity and solve,
 
If you're still having trouble, use trig.
 
Yeah, I figure this is really simple. We've had one class and this is the first homework. I haven't had math in 4 years and even then I struggled. Not seeing how to do this but I'll figure it out somehow. Thanks.

I did make a diagram, have the hypotenuse and 30m/s labeled but that's it.

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}...
