As the rope pulls the block, the block pulls back with equal force in the opposite direction. So I'll go with 2p. But I'm not sure of that.. Anyone?

see just take mass of rope plus the block and then apply all formulas
anonymous
  • anonymous
like joint bodies
anonymous
  • anonymous
they have reaction forces between them

(M+m)a = p

?

| r | <-------rope -------- | r | < --------block so r is the force exerted by the rope on the block r = m(block)a and from the rope equation
anonymous
  • anonymous
f (force applied ) + r = m(rope)a now get r

Maybe I should thing twice about taking physics. lol
anonymous
  • anonymous
lol no you should take it

I don't really understand why its F+r on the left side there..
anonymous
  • anonymous
the thing is block | rope |---------------------- R<-| ---------> R |---------------------- | --------------------------------------------------
anonymous
  • anonymous
R is the reaction force or contact force
anonymous
  • anonymous
------------------------------------ ---->R |--------->p ------------------------------------ P + r = m(rope)a

Are we speaking of the force the rope is "feeling"?
anonymous
  • anonymous
Yeah
anonymous
  • anonymous
OHHHHH
anonymous
  • anonymous
I didn't draw the normal or perpendicular forces
anonymous
  • anonymous
but it says "what will be the force by the rope ON THE BLOCK.. lol so I thought that means, what the block is feeling>>
anonymous
  • anonymous
R is the force for the block from the rope
anonymous
  • anonymous
now take a careful look the only force that rope and block have is the R so hence r is the one were looking for

Is there a name for this type of problem so I can go concentrate on them?

try Rop-mass.......... I don't know i didn't solve them much
