NT51-QRT104: TWO OBJECTS— GRAVITATIONAL FORCE ON EACH
The drawing to the right shows an object (labeled B) that has mass m. To the left is another object (labeled A) that has mass 2m. Identify the pair of force vectors (the arrows) that correctly compare the gravitational force exerted on A by B with the gravitational force exerted on B by A

You are asked to help design a new type of loop-the-loop ride. Instead of rolling down a long hill to generate the speed to go around the loop, the 310 kg cart starts at rest(with two passengers) on a track at the same level as the bottom of the 10
m radius loop. The cart is pressed against a compressed spring that, when released, launches the cart along the track around the loop.
Part A
Choose a spring of the appropriate spring constant to launch the cart so that the downward force exerted by the track on the cart as it passes the top of the loop is 0.2 times the force that Earth exerts on the cart. The spring is initially
compressed 6.0 m.

- You operate a restaurant that has many large, circular tables. At the center of each table is a Lazy Susan that can turn to deliver salt, pepper, jam, hot sauce, bread, and other items to diners on the other side of the table. A fancy flower arrangement is located at the center of each Lazy Susan, and the turning of the flower arrangement is beautiful to you. Because of your interest in model trains, you decide to replace each Lazy Susan with a circular track on the table around which a model train will run. You can load the various condiments in the cars of the train and press a button to operate the train, causing the train to begin moving around the circle and deliver the load to your fellow diners! The train is of mass 1.96 kg and moves at a speed of 0.18 m/s relative to the track. After a few days, you realize that you miss the beautiful turning flower arrangements. So you come up with a new scheme. You return the Lazy Susan to the table and mount the circular track on the platform of the Lazy Susan, which has a friction-free axle at its center. The radius of the circular track is 40.0 cm (measured halfway between the rails) and the platform of the Lazy Susan is a uniform disk of mass 3.00 kg and radius 48.0 cm. You finally equip all of your tables with the new apparatus and open your restaurant. As a demonstration to the diners, you mount one salt shaker and one pepper shaker, having a mass of 0.100 kg each, onto a flatcar and push the button to deliver the condiments to the other side of the table! How long does it take to deliver the condiments to the exact opposite side of the table? Ignore the moment of inertia of the flower arrangement, since its mass is all close to the rotation axis.arrow_forwardCase Study For each velocity listed, state the position and acceleration of the rubber disk in Crall and Whipples experiment (Figs. 16.316.5).

A short bridge leads you to a scenic platform overhanging a drop. As soon as everyone in your group has gotten on the platform, your guide closes a gate and pushes a switch. You realize that the platform is attached to a pivot by a 10 m arm. The platform (12 m × 12 m) swings around to land against another landing 200° around the circle from your initial position. The swing takes 1 minute. Take the swing as travelling clockwise relative to the viewer. a) What is the average angular velocity of the platform? b. What is the distance travelled by a person in the middle of the platform during the swing? c.
