maybe 5" x 4" 20'x16' or any other 5:4 ratio, depending on the scale.
PE -> KE mgh = 1/2 mv^2 gh = 1/2 v^2 v = √2gh = √(2*9.8*7.63) = 12.23 m/s note that the mass doesn't matter. Only the height contributes to the speed.
I think you need to check out (c)
actually, that would be -1.96
AP Physics - correction
the diver's air speed is v = 9.8t make that correction and redo the board height.
the upward acceleration from the water is a=F/m = 1480/67 = 22.09 m/s^2 The diver's speed on entering the water is v = √(2as) = √(2*22.09*4.7) = 14.4 m/s In the air, the diver's speed is v = 4.9t^2, so he fell for t = √(14.4/4.9) = 1.71 seconds The di...
if we have x servings of granola y servings of juice we want to minimize c = .89x + .79y subject to 140x + 60y >= 160 31x + 13y >= 40 0x + 100y >= 70 x=1 y=0.7 c=1.44
a couple has just learned that their daughter has hemophilia. they alredy have a son who does not have the disease.what are the genotypes of the couple
yes if f(t) is his elevation at time t ascending, f(8) = 0 f(16) = h if g(t) is is elevation at time t descending, g(9) = h g(15) = 0 f(t) = 0 + h/(16-8) (t-8) g(t) = h - h/(15-9) (t-9) so, we want 0 + h/8 (t-8) = h - h/6 (t-9) We can, without loss of generality, set h=1, so t...
no direct variation. That pesky -2 on the right queers the deal. Also, there is a typo, because the x is missing.
