fixed thank you

hello i would like to understand something, i found the right answer but there is still something i don't understand. here is the figure and here is my correct solution what i don't understand is why F(3,Q) is 3kQ/r^2 i mean why is the 3? i only calculat the force between q3 and Q so why...

about the first question i was thinking that because impulse formula is J=F*(t-t0) and the force isn't constant then if i calculate the change in the force and multiply it by the change of time it will be alright about the second question i was not able to calculate the area between t = 12 to...

hello i would like to get some help with this problem. At first it try to calculate the impulse by the area but i found it too difficult Then i try to solve it by the forumla J= F(t-t0), but the problem is that i don't know what F is so i try to solve it like this F10) = 8 F(33) = -13 so EF =...

ohh true I was confused thank you very much

i would like to get some help and to understand why my answer is incorrect , here is how i did the first and second part. about the first part i did it right but i don't understand what I am doing wrong in the second part i tried -k and i get -23.997 and i also try +k and i get 23.997 but they...

i understand so how i need to change my calculations to get to the right answer

Fspring= x*k = 0.037*531 i don't see how the friction is relate because the only force is Fs-mg=0

i would like to understand why my answer is incorrect and how i need to solve this problem

i try this i did (-5.8*(9.81-0.41))/711 and get -0.0766m and its still the wrong answer

i would like to understand why my answer is incorrect i don't know what I am doing wrong i would like for some help

hey i would like to understand something, i solve this question but i don't understand why my answer is right, first of all we learn that in problems like this we need to disassemble into components the mg and that what i try to do here but i didnt get the right answer so then i try to do same...
