...hello?

someone please help!

so i have this problem with a block sitting on a horizontal surface and this block(m1) has the weight of 420 N. This block is connected by a string to a pulley and then connects to another block(m2) that is hanging from the pulley. The weight of the hanging block is 190 N. Ignore all...

is this right/?

i think ill give up now...i am dumb..............................

so : 14.6118 = 2.1a so : 6.958 = a

do i plug in 2.1 or 21 for m?

the normal force=mg so : 2.1(9.8)=20.58 N so : 0.71(20.58)=ma so : 14.6118=ma

i might as well give up...i am horrible at physics

Fg=mg =21(9.8) =205.8 N =(2.1)(9.8) =20.58 so i know: Ns * Fn = ma 0.71*Fn=205.8N(a)

isnt the acceleration of the large and small cube the same..? but they don't tell me the acceleration...

well it is a picture of a crane that has a string coming down that splits into two cables one connecting on one side of the beam and the other connecting to the other side of the beam. A 70 degree angle is formed between one side of the beam and the string and likewise on the other isde of the...

My teacher gave me this problem but we haven't even gone over two body probles with tension...especially those where one object is going another direction... 1) The drawing shows a large cube (mass = 21 kg) being accelerated across a horizontal frictionless surface by a horizontal force P. A...

it should be attached...

someone please help...6087.9 isn't the right answer and I've tried this problem 1000 times!
