Re: impulse/momentum



This one is from Halliday Resnick and Walker, problem 10.17, which I
quote: "A stream of water impinges on a stationary 'dished' turbine
blade. The speed of the water is v, both before and after it strikes the
curved surface of the blade, and the mass of water striking the blade per
unit time is constant at the value u.

"speed of the water is v, both before and after" Wow. Very strange water.
