I was sitting in a spa hot tub and some chute coming down from a chute was hitting my knee.
I'm wondering 2 things
- a) How do I calculte how high the water goes when it hits my knee
- b) How much water does it takes before my knee start moving.
Let's say the water move at $1\over2 m/s$
for B I got
The water flow is about 60 cm large and 4 cm of height
$M = $ 240 Cubic centimeters = 0.24 Kilograms $F = $ $0.24 \cdot $ $1/2 m/s \over 1 second $
edit: why do you tagged this as a homework. geez. I'm trying to introduce myself to physics with some random real world situation. Just want to know want should I use to calulate.
