I got the first half of this problem, I'm just stuck on the others. Please take your time to help Thanks a lot!

Problem: A 5kg penguin sits on a 10kg sled. A horizontal force of 45 N is applied to the sled, but the penguin attempts to impede the motion by holding onto a cord attached to a wall. The coefficient of kinetic friction between the sled and snow as well as that between the sled and the penguin is .2

b) Determine the tension in the cord and c) the acceleration of the sled

if you try to solve for the tension using F=ma, do you could both the weights as the normal force? or do you only count the penguin's weight?

Thanks
