Enjoy, How did you find the answer to question on the yoyo I got it wrong, and question number 2 on torque. Thanks.
Answered by enjoy
you mean a= F*R(1-(r/R))/((I/R)+(m*R))
this is wrong?? check your figures and then plz reply man!
Answered by jennifer
yes i got it wrong too
Answered by Mets
Hi enjoy, I got the acceleration correct, but the x component of the friction force incorrect in part b.
Question no. 2 on torque is confusing from the top view CW or CCW. Thanks.
Answered by enjoy
IS this expression correct
a= F*R(1-(r/R))/((I/R)+(m*R)) ??
if it is then friction f
f = force-(m*a).
reply fast

Hi, Enjoy. I responded but I do not know what happened. f=force - (m*a) , 22-(2)*(12.83 3)=
-3.666. x-componet in negative x direction. I am
up to my last chance as on most problems. I need help on question no.1. Thanks.
