- A pendulum bob is attached to a string and allowed to swing. Which of the following statements is true with correct reasoning about the magnitude of the force the string exerts on the bob Fs on B and the magnitude of the force Earth exerts on the bob FE on B at the very bottom of the pendulum's swing? FS on B = FE on B because the bob is moving at a constant speed at that point so the forces exerted on it must be balanced. FS on B > FE on B because the string would not be able to support the bob if it were not. FS on B > FE on B because the bob is accelerating upward at the bottom of its swing. Fs on B=FE on B because of Newton's 3rd LawThe moon is held in its orbit around Earth by gravity. Earth has a mass approximately 78 times greater than the mass of the moon. Which of the following is true? The force of Earth acting on the moon is greater than the force of the moon acting on Earth. The force of the moon acting on Earth is equal to the force of Earth acting on the moon. The force of Earth acting on the moon is less than the force of the moon acting on Earth. The force of the moon acting on Earth is greater than the force of Earth acting on the moon.9:58 PM Sun Feb 27 blackboard.albany.edu A 令74% O exactly as strong as the force of gravity on a 3-kg mass QUESTION 3 1 points A rocket is launched vertically from the Earth, and the thrust (pushing force) from the engines is directed upward, and has a magnitude of 5.00 x 106 N.

Assume the force the floor exerts on the player is constant.What is the force the floor exerts on the player? Give answer in lbs. (Let 4.45 N = 1 lb., 1 inch = 2.54 cm)A flea jumps by exerting a force of 1.20×10−5 N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 0.500×10−6 N on the flea. (a) Find the direction of the acceleration (relative to the +y axis) of the flea if its mass is 6.00×10−7 kg. Do not neglect the gravitational force.
- A passenger is standing on a scale in an elevator. The building has a height of 500 feet, the passenger has a mass of 80 kg, and the scale has a mass of 7 kg. The scale sits on the oor of the elevator. You may take g = 10 N/kg. While it is accelerating downwards hat does the scale read (in newtonsWhat is the direction of the force exerted by the car on the passenger as the car goes over the top of the amusement ride pictured under the following circumstances: (a) The car goes over the top at such a speed that the gravitational force is the only force acting?

- HelpA 270-kg object and a 570-kg object are separated by 4.90 m. (a) Find the magnitude of the net gravitational force exerted by these objects on a 32.0-kg object placed midway between them. 1.323 × Draw a picture of the three objects, including the forces exerted on the third. N (b) At what position (other than an infinitely remote one) can the 32.0-kg object be placed so as to experience a net force of zero from the other two objects? 2.61 You appear to be assuming the answer will be a simple ratio of the masses. You must look very carefully at the equations before assuming a simple ratio holds. m from the 570 kg mass toward the 270 kg massConsider the following statement: “The normal force on an object is always equal to the weight of the object.”Select all the reasons that this statement is false . The normal force is not always parallel to the force of gravity The normal force is independent of the force of gravity The normal force is only equal to the weight of the object when sitting on a horizontal surface and there are no other forces in the y-direction except gravity The normal force causes an acceleration and therefore does not interact with gravity
