Can someone tell me how to figure this out. Fido weighs 120N & carries Trixie who weighs 40N on her back. The support force on fidos feet is. 160n - 40n - 120n -more than 160n

    just remember that weight is a force that acts down. In this case you would add both of the weights.

    120n + 40n = 160 n
