Consider the following distribution of objects: a 4.00-kg object with its center of gravity at (0,0) m, a 5.20-kg object at (0,5.00) m, and a 5.40-kg object at (4.00,0) m. Where should a fourth object of mass 9.00 kg be placed so that the center of gravity of the four-object arrangement will be at (0,0) ?
* A tall, cylindrical chimney falls over when its base is ruptured. Treat the chimney as a thin rod of length 63.0 m. Answer the following for the instant it makes an angle of θ with the vertical as it falls. 1. Calculate the angular speed at the angle θ =50.0°. 2. Calculate the tangential speed at the angle θ =50.0° of the top. 3. Calculate the tangential speed at the angle θ =50.0° at the center of mass of...
Learning Goal: To be able to find the center of gravity, the center of mass, and the centroid of a composite body. A centroid is an object's geometric center. For an object of uniform composition, its centroid is also its center of mass. Often the centroid of a complex composite body is found by, first, cutting the body into regular shaped segments, and then by calculating the weighted average of the segments' centroids. An object is made from a uniform...
A flowerpot is knocked off a balcony 23.9 m above the sidewalk and falls toward an unsuspecting 1.93 m tall man who is standing below. How close to the side walk can the flower pot fall before it is too late for a warning shouted from the balcony to reach the man in time? Assume that the man below requires 0.138 s to respond to the warning, and the velocity of sound in air to be 341 m/s. The acceleration...
the diagram below. A person who is1.1 m tall throws a bell with a speed of 26 m/s at an angle of 12 degrees above the horlzontal, as shown h-1.1 m, v 26 m/s, 8-12 degrees Use the acceleration due to gravity as g 10 m/s What are the x and y components of the initial velocity? mys THes 0/2 Subit Anw What are the x and y components of the ball's velocity when it is at its maximum height?"...
An owl is carrying a mouse to the chicks in its nest. It is 4.00 m west and 12.0 m above the center of the 30 cm diameter nest and is flying east at 3.50 m/s at an angle 33° below the horizontal when it accidentally drops the mouse. Will it fall into the nest? Find out by solving for the horizontal position of the mouse (measured from the point of release) when it has fallen the 12.0 m. X...

An owl is carrying a mouse to the chicks in its nest. It is 4.00 m west and 12.0 m above the center of the 30 cm diameter nest and is flying east at 4.50 m/s at an angle 29° below the horizontal when it accidentally drops the mouse. Will it fall into the nest? Find out by solving for the horizontal position of the mouse (measured in meters from the point of release) when it has fallen the 12.0...
An owl is carrying a mouse to the chicks in its nest. It is 4.00 m west and 12.0 m above the center of the 30 cm diameter nest and is flying east at 3.00 m/s at an angle 27° below the horizontal when it accidentally drops the mouse. Will it fall into the nest? Find out by solving for the horizontal position of the mouse (measured from the point of release) when it has fallen the 12.0 m. =...
