A 1 kg box of donuts weighs 9.8 N, and it is hanging at rest on a length of twine suspended from the ceiling of police headquarters. The force that forms a “third law pair” with that weight force is 9.8 N, upward, exerted by the twine on the box 9.8 N of upward gravitational force exerted by the box on Earth itself 9.8 N downward, from the box on the twine 9.8 N, downward, from the twine, acting on...
1. A 25 kg child riding a bicycle at 9.1 m/s slams on their brakes to stop in 1.7 s. What is the magnitude of the net force applied by the brakes to stop the child? 2. A 0.5 kg book is resting on a table. A student leans their hand on the book, exerting a 19 N downward force on the book. What is the magnitude of the Normal Force acting on the book? (Use 9.81 m/s2 for gravitational acceleration.)
Two identical books are stacked on a table. A third identical book is then placed on top of the first two, causing an increase in the normal force exerted by the bottom book on the middle book. Which of the following is a correct explanation for the increase in this normal force? A-The normal force on an object is equal in magnitude and opposite in direction to the force of gravity on that object. B-The addition of the top book...
