no
what do you mean?
wrong
average a = (final velocity-initial v)/time elaspsed = (2800rpm/900rpm)/4.5s
76
T=mg+ma mg = weight = 63.o*9.81 ma= 63*.5 then add to get T
it's one cable, with a crate tie at the bottom and a worker in the middle of the cable between the crate and whatever the top end is, and he is climbing upward with a=.620m/s^2
(X-14)^2+X^2 = 26^2 solve for x and x-14
mutiply out the 2 factors and subrtract 91 from both side to equate equation to zero then solve for root

sun------------moon I I I Earth I still don't get the problem...the resultant vector founded did not solve it please help
will it hit? use final velocity of 0 presuming that it came to a halt find the time elasped for it to stop using acceleration = change in v over change in t use the time to find how far both have traveled... yes it will hit it;s an equation of what time
intial Vy=0 (since it's thrown horizontal) change in y = -29.0m Ay=-9.81 m/s^2 find the time used by equate : change in Y= intial Vy times time +1/2 Ay times time squared so -29.0=1/2(-9.81)t^2 t^2 = .91s so t=2.43s since time used for y is same as x
4.0 N since it's oppo directions so the magnitude of net force is absolute valure of the 2 numbers
the initial V is the greatest , ignore air resistance
first need to change all fraction into same D so 49x over 2(7x+1) can muliply by x over x become 49x^2 over 2x(7x+1. change the third fraction also into same D by mutiplying by 2(7x+1) over 2(7x+1) so becomes 22(7x+1) over 2x(7X+1) then just add n subrract
computer programming stuff n also used on like graphing design stuff
supplement angles add up to be 180 so it'll be 180-(3x-16) =196-3x
since in a triangle 2 sides add together must be greater than 3rd and 2 sides subtract each other must be less than third then the range of 3rd side is : 11-8
range is value of y so y=3x-2 substitute each following 1, 7, 13, 16 , and 19 into y and solve for x should be the domains x {1,3,5,6,7 }
if an object's velocity is in the same direction as it's acceleration then the speed is increasingex: dropping a ball,negative velocity n negative acceleration so speed increases opposite direction then object will slow ex: throwing ball upward -velocity
