A cable is lifting a construction worker and a crate The weights of the worker and crate are 915 and 1430 N, respectively. The acceleration of the cable is 0.620 m/s2, upward. what is the tension in the cable below the worker? what is it above the worker?

A water skier has a mass of 73 kg. Find the magnitude of the net force acting on the skier when she lets go of the tow rope and glides to a halt in 20 s.

A paraglider is flying horizontally at a constant speed. Assume that only two forces act on it in the vertical direction, its weight and a vertical lift force exerted on its wings by the air. The lift force has a magnitude of 1900 N. For both questions, t...

In a cargo plane, the center of gravity must be between the front and rear landing gears in order to maintain a torque equilibrium. The front landing gears help counteract the torque provided by the rear landing gears in this case. A jet transport has a w...

you need to put this in synthetic division take the coef from power of greatest to least 1 2 -109 -110 and use factors of -110 to try -1 works so (X+1) is a factor of equation rewrite: (x+1)(X^2+X-110) find root of (X^2+X-110) COME TO be -11,10 so factor...

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...

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 }

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<X<11+8 x is in open interval of 3 n 19 (3, 19)

supplement angles add up to be 180 so it'll be 180-(3x-16) =196-3x

computer programming stuff n also used on like graphing design stuff

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 subrrac...

the initial V is the greatest , ignore air resistance

4.0 N since it's oppo directions so the magnitude of net force is absolute valure of the 2 numbers

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 chan...

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 u...

sun------------moon I I I Earth I still don't get the problem...the resultant vector founded did not solve it please help

second word is quiero

mutiply out the 2 factors and subrtract 91 from both side to equate equation to zero then solve for root

(X-14)^2+X^2 = 26^2 solve for x and x-14

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

T=mg+ma mg = weight = 63.o*9.81 ma= 63*.5 then add to get T

average a = (final velocity-initial v)/time elaspsed = (2800rpm/900rpm)/4.5s

what do you mean?

Yes it is A,C,D,B,C!

@*~^-^~* I got a %100 on relationships quick check!

@LegaciesFan is right for the Analyzing Theme Quick Check, ty!

100% thank you @Why did nobody answer 🥲

bruh 20022 goin on 2023 and still no answers

oh ok I get it thanks
