ganeshie8 (ganeshie8):
i think the rod accelerates when it is in contact with the plank, then we should be able to find the final speed of the rod when it reaches the height of plank
Parth (parthkohli):
correct! to determine vertical acceleration of the rod, equate the component of accelerations along the common normal.
