• What are the action and reaction forces in the case of an object falling in a vacuum?
• Two 10 N weights are attached to a spring scale as shown below. Does the scale read 0, 10, or 20 N, or give some other reading? (Hint: Would it read any differently if one of the ropes were tied to the wall instead of to the hanging 10 N weight?
• Two people of equal mass attempt a tug-of-war with a 12-m rope while standing on friction-less ice. When they pull on the rope, each of them slides toward the other. How do their accelerations compare, and how far does each person slide before they meet?
• When you jump vertically off the ground, what is your acceleration when you reach your highest point?For more information on Action and Reaction Forces read this:org/wiki/Reaction_(physics)”>https://en.wikipedia.org/wiki/Reaction_(physics)
