6. You are standing in a park under a tree contemplating Newton's laws. According to Newton's third law, the reaction force to the gravitational force the Earth exerts on you is O The normal force the ground exerts on you O The gravitational force you exert on the Earth The static friction force you exert on the ground O The normal force you exert on the ground8a. Two pucks with mass my = 0.05 kg and me = 0.08 kg are sitting on a frictionless table connected by a thin, light string of length 0.40 m. They are made to spin about a common point on the string such that a complete rotation takes 1.5 s. m2 m1 Which mass moves in a smaller circle? O m1 O m2 8b. What is the angular velocity wj and w2 of each mass? Please give your answer in Hz. W1: Enter answer here 8c. W2: Enter answer here8d. What are the tangential velocity v1 and v2 of each mass? The centripetal acceleration aj and a2? Please give your answer in my s for the velocity and m /s' for the acceleration. 21: Enter answer here 8e. U2: Enter answer here 8f. a1: Enter answer here 8g. 02: Enter answer here7. You decide to hang pictures of your favorite physicsists in your home. I don't see my picture there, but whatever. Each is hung with a single, continuous wire, and you arrange the wires in three configurations shown. Each picture has the same mass. The magnitude of the tension in the wire will be O Smallest for the left picture. Largest for the left picture. Largest for the middle picture. O Smallest for the right picture. Largest for the right picture.Sh. What is the tension in the string? Please give your answer in N. Enter answer here Si. How far from m j on the string is the point of rotation? Please give your answer in m. Enter answer here9. An object is moving in a circle with velocity v as shown in the figure below, and the magnitude of the object's speed is decreasing. B D A
