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.
Find the acceleration of the system for m1>m2, m2>m1. Assume negligible friction in the pulley. The incline is a right triangle <(theta). The coefficient of friction of the surface=*m
that is supposed to be a meew, a little squiggly m.
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.
