OK shot in the dark here but here is my question prefaced with a small back-story.
Im a undergrad in mechanical engineering program. I am currently having a bit of trouble in Dynamics class. A lot of people who are much smarter than me say its nothing more than applied physics. Like some guys...
Homework Statement
Suppose that the Celsius temperature at the point (x, y) in the xy plane is T(x,y) = xsin(2y)
and that the distance in the xy plane is measured in meters. A particle moving clockwise around the circle of radius 1m centered at the origin at the constant rate of 2 m/s
a...
i figured it out, only a small mistake
for anyone who may encounter this exact scenario
i was forgetting dt/ds as 1/lvl where as ds/dt is mag v
small dumb error
"box of primes" over l V X a l ^2
Homework Statement
Find B, and t for these space curves (t = torsion)
r(t) = (3sint)i + (3cost)j + 4tk
Homework Equations
Ok, so in my textbook i have two different equations to find the answer to this.
the "box of primes" over l V X a l ^2...
just wanted to pop back in here and say thanks for the help, was just getting frustrated. ended up getting a decent grade in the class thanks to your help and others from this site.
never taking a calc based phys course during the summer again. I need more time to learn LOL
i don't understand what you mean.
the block is moving up the slope at .64 ms
its Fg is 9.8 * 2.1 right?
so i have a, and fg right there.
the normal force is the force the slope is pushing back up into the mass right?
moving in the x direction is Fg * cos 60 right? or Fg sin 60...
i didnt use f = ma for the left one. I thought that 20.58N * sin60 would give the force parallel to the slope
getting 17.83 and then 20.58 cos 60 = 10 . 29 N would the the normal force
so what... then i have ... Fnet = ma~
t1 + 20.58 + 10.29 = (2.1)(.64)
(all the forces?)
is that right...
are you saying it SHOULD be for one mass only or that was my mistake?? sorry
again, thank you so much i feel closer already.
this is what i have drawn out so far
