The two spheres A and B each have a mass of 400 g. The spheres are fixed to the horizontal rods as shown in (Figure 1) and their initial velocity is 2 m/s. The mass of the supporting frame is negligible and it is free to rotate. Neglect the size of the spheres. ▾ Part A If a couple moment of M = 0.9 N-m is applied to the frame, determine the speed of the spheres in 3 s. Express your answer to three significant figures and include the appropriate units. igure I'M -0.3 m- -0.3 m- D 1 of 1 Value Submit Request Answer ? Units < Return to Assignment Provide Feedback

Problem 1:   The figure shows a small sphere of mass m a distance D from the edge of a uniform rod of length L and mass M placed perpendicularly to the rod. The left edge of the rod is placed at the origin of an xy coordinate system. The x-direction points to the right, and the y-direction points up in the figure shown.The rod has a mass of 6.1 kg and the small sphere's mass is half the mass of the rod. The distance D = 1.4 m and the rod has a length of 1.4 m. What is the magnitude of the gravitational force, in newtons, of the ball?

F The force F = 460 N acts on the frame. Resolve this force into components acting along members AB and AC, and determine the magnitude of each component. Given that a = 34° and ß = 47°, The magnitude along AB is (round to one decimal place): The magnitude along AC is (round to one decimal place): N

3 Given a wire frame in the shape of a right-angled triangle of vertical side a, of total mass m, with one side perpendicular to the z axis. The frame rotates about the z-axis with an angular velocity w. Find the L₂ component of the angular momentum of the frame.

Two 150 kg lead spheres are suspended from 100-m-long massless cables. The tops of the cables have been carefully anchored exactly 1 m apart. Part A By how much is the distance between the centers of the spheres less than 1 m? Express your answer to two significant figures and include the appropriate units. Ax = ¹"¯μA Value Units ?

A narrow uniform rod has length 2a. The linear mass density of the rod is p. so the mass m of a length of the rod is pl. Part A A point mass is located a perpendicular distance from the center of the rod. Calculate the magnitude of the force that the rod exerts on the point mass. (Hint: Let the rod be along the y-axis with the center of the rod at the origin, and divide the rod into infinitesimal segments that have length dy and that are located at coordinate y. The mass of the segment is dm = pdy. Write expressions for the I- and y-components of the force on the point mass, and integrate from a toa to find the components of the total force). Express your answer in terms of the gravitational constant G and some or all of the variables m, p, a, and r.
