The action force is the balloon pushing the air out. What is the magnitude of the reaction force of the air pushing on the balloon?

Since the action force is -3 the reaction force will be 3. Since the net force has to add up to 0.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
