Step-by-step explanation:
Here we should think of the exact moment the drumstick and the drum come in contact and the forces involved. There is a force that stops the stick from going through the drum, this is the normal force that the drum exerts on the stick. There is also an equal and opposite force that the stick exerts on the drum, this is the sum of a normal force (stick to drum) and the force that gravity exerts on the drumstick (assuming drum is under the stick).
normal force (drum to stick) = normal force (stick to drum) + gravity on stick
