Hey there,
I need a nudge in the right direction on two problems. Can you anyone help me out.
I will post the other question seperately in a few :)
Here we go:
1) A bead is sliding along a stiff wire track. The bead is released from rest at point A and comes to a stop (momentarily) at point B. The hieghts of these points above the horizontal are 50 cm and 30 cm, respectively. The length of the wire between then is 400 cm. If the bead is 3.0 g and the frictional force is approximatley constant throughotu the motion, find the value of the frictional force. Watch your units!
WOW... brainblower!
I take it they mean "cm" and "g" arent compatible so some conversions are needed. then... what...
I was thinking this was momentum problem..but...not sure..
can I have a nudge ??
