Idk if this is what u are looking for but i hope this help.:)
The first thing you should know is that the friction force is equal to the coefficient of friction due to normal force.
Therefore, clearing the normal force we have:
The friction is 565N.
(565 / 0.8) = 706.25N. weight.
For number one she is going to observe the contraction of the ballon
For number two she is going to observe the expansion of the ballon
