AI Thread Summary
A car traveling due east at 35.0 km/h experiences rain falling vertically, creating an angle of 55.0° with the vertical on the windows. To solve for the rain's velocity in different reference frames, the first step is converting the car's speed from km/h to m/s, resulting in approximately 9.72 m/s. The problem involves applying trigonometry to determine the rain's horizontal and vertical components based on the given angle. A diagram can help visualize the relationship between the car's velocity and the rain's trajectory. Understanding these components will lead to calculating the rain's velocity relative to both the car and the Earth.

A car travels due east with a speed of 35.0 km/h. Raindrops are falling at a constant speed vertically with respect to the Earth. The traces of the rain on the side windows of the car make an angle of 55.0° with the vertical. Find the velocity of the rain with respect to the following reference frames.



1. the car : ___m/s
2. the Earth: ___m/s



I don't know how to solve this problem. I am bad at physics and I can't find any formulas to save me. If some could help walk me through it, help me, or point me in the right direction, that'd be great. Thanks.

first need to convert units from km/h to m/s. Then it is all trigonometry. Draw yourself a diagram and label you knowns and unknowns. Post what you come up with.
 
Ok, I converted 35km/h to m/s and I got 9.72222223. And I know the angle is 55 degrees. So, if I draw a triangle, I would label the angle between the hypotnues and adjacent 55 right?
I'm not sure what I am really supposed to draw or how I can convert 9.72222223 into the velocities I need.
 
Like, what formulas do I use to find the velocity in this problem?

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 '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...
