[SOLVED] force and momentum
this is my homework problem and me and my freinds are kinda stuck
the problem reads:
The great limestone caverns were formed by dripping water.
The acceleration of gravity is 9:81 m=s^2:
If water droplets of 0:73 mL fall from a height of 16 m at a rate of 17 per minute, what is the average force exerted on the limestone floor by the droplets of water during a 3 min
period? Answer in units of N.
now we are on the subject of momentum and we know we have to find
F = dp/dt
however we don't know how to take the derivative of the momentum equation because we don't know where the rate of dropping fits in
any help would be greatly appreciated. to get us on the track
