Rain hits you at 5m/s.
They make an angle of arc-tan(4/3) with the vertical.
To get this, draw the two vectors with their tail together, and find the resultant.

I think it is a mistake to asume that the raindrop hits face as it is a vertical surface, and that the person is runing "horizontally". The question isn't precise enought to give an exact result.

4 m/s, if I am facing straight ahead.
3 m/s, if I am looking up.
They do not have a horizontal component.
This is provided by me, if I am facing straight ahead while running.
Which I would be-it is the smartest option.
e.g. I could run into them at 4 m/s or they
could fall on my face at 3 m/s.

5 m/s. use the pythagorean theorem for this one... c = square root of (a squared + b squared).
wow, are you really running raster than rain falls?

Yup. 5 m/s allright.
Now *you* figure out how we got that answer.
And do it *before* your next exam âº
