• 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 frictionless 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?
An object has an acceleration of 6.0 m/s/s. If the net force was tripled and the mass were doubled, what is the new acceleration?
