Identify ONE FORCE acting on the PANDA sitting in the tree (OTHER THAN GRAVITY), and identify the AGENT, RECIEVER, and EFFECT of that force.

Anne applies a force on a toy car and makes it move forward. what can be said about the forces acting on the toy car at the moment anne applies the force?

The crank oa rotates in the vertical plane with a constant clockwise angular velocity ω0 of 5.6 rad/s. for the position where oa is horizontal, calculate the force under the light roller b of the 10.6-kg slender bar ab.

Can anybody me with this? ? (picture included.)
