As in the figure, a uniform sphere of mass = 0.8 kg and radius r = 4.2 cm is supported by a string (of negligible mass) attached to a wall (whose friction can also be ignored). The center of the sphere is a vertical distance L = 9.5 cm below the attachment point of the string. Find the force on the sphere from the wall.
Your answer should be in N, but enter only the numerical part in the box.

A rod of length L and negligible mass is attached to a uniform disk of mass M and radius R (see figure below). A string is wrapped around the disk, and you pull on the string with a constant force F. Two small balls each of mass m slide along the rod with negligible friction. The apparatus starts from rest, and when the center of the disk has moved a distance d, a length of strings has come off the...
The sphere of mass M and radius R is rigidly attached to a thin rod of radius r that passes through the sphere at distance ½R from the center. A string wrapped around the rod pulls with tension T. (Figure 1) Part A Find an expression for the sphere's angular acceleration. The rod's moment of Inertia is negligible
Two objects are moving in the xy-plane. Object A has a mass of 3.2 kg and has a velocity vA = < 2.3 m/s, 4.2 m/s > and object B has a mass of 2.9 kg and has a velocity vB = < -1.8 m/s, 2.7 m/s > . What is the total momentum of the system? A uniform sphere of radius 2R has a spherical cavity of radius R cut out of it. The center of the cavity is...
A 2.000 m long horizontal uniform beam of mass 20.00 kg is supported by a wire as shown in the figure. The wire makes an angle of 20.00 degrees with the beam. Attached to the beam 1.400 m from the wall is a ball with a mass of 40.00 kg. What are the vertical and horizontal components of the force of the wall on the beam at the hinge?
A solid uniform sphere of radius 0.76 cm and a mass of 0.87 kg is held against a spring compressed a distance of 6.0 cm from its resting length. After release, the sphere leaves the spring and rolls down the flat, horizontal table with a translational velocity of 3.9 m/s. a) What is the force constant of the spring? b) If the ball then rolls up a ramp inclined at 22 degrees, how far along the ramp does it travel?
