Physics

Here's a little bit of physics.(my favorite equations)
d=r(t) or x=v(t) and x=Xo+Vo(t)+1/2(A)(T**2)


Here's a physics problem.



W=m1g
W'=m2g
Wx=m1g(cos(theta2))
Ffr=*m(Fn)=*m(m1g)(sin(theta2))
Wy=m1g(sin(theta2))=Fn


for m1>m2:

sum of forces in the Y direction=Wx-W'-Ffr

(m1+m2)a=m1g(cos(theta2))-m2g-*m(m1g)(sin(theta2))

a =m1g(cos(theta2))-m2g-*m(m1g)(sin(theta2))/(m1+m2)


for m2>m1:

sum of forces in the x direction=W'-Wx-Ffr

(m1+m2)a=m2g-m1g(cos(theta2))-*m(m1g)(sin(theta2))

a =m2g-m1g(cos(theta2))-*m(m1g)(sin(theta2))/(m1+m2)


There you have it, something you've always wanted to know.
