i didn't get that....
ohh... nevermind!
but.. what formula do i use?
thanks
thank you
thanks!
thanks!
yeah you were right thanks.
get it right thanks
yeah the only thing you did wrong was the final answer it should be 34.72E3 W
thanks!
yep i noticed that =P
could i get some help damon
yeah its still not working i did that i think it wants us to more of an kinetic energy or work method to solve for it.
they want us to use the height somehow.
ok well the elements that are the least reactive are located at the furtherest right side they are called the halogens or the noble gases and the least reactive are on the other side and they are called the alkali metals the non-metals are on the left side
ha wrong question sorry.
i've gotten 41.57 41.92 and 5.68 when i only used the mass of the bullet
yeah you wanna do that and tell me what you get or just tell me what you used for the masses because i keep getting wrong.
1 false 2 false 3 false 4 false 5 true 6 true that should be right its capa. =]
i don't think the conversion will be necessary because it wants the answer to be in scientific notation
this was what i did and it worked for me ok but the Fb*d the d=0 so that cancels out so i have 83.7(-9.8)(3.2)+30.5(-9.8)(2.25)-Fa(4.5) where the guy weighs 83.7 Kg the board weights 30.5 kg the distance between the saw horses is 4.5 m and Fb of the second
its cool the answer is 732.57 N i got it =]
due to natural selection the amount of birds that have lived throughout the 20 year period have been the birds with the bigger beaks because the food they need for survival burrows further into the ground therefor the lengths of the beaks for the birds
ok so i solved all that out and it said i was wrong and told me this There are two forces acting on the saw horses. One is due the weight of the board. This is evenly distributed between the two saw horses, because the board is placed symmetrically on
I still don't quite understand how you got 2.25 meters...
yeah didn't understand that hence me posting it again!
