Q. A uniform disk turns at 4.3 around a frictionless spindle. A nonrotating rod, of the same mass as the disk and length equal to the disk's diameter, is dropped onto the freely spinning disk . They then both turn around the spindle with their centers superposed. What is the angular frequency in of the combination?
Question on constant speed
A 53 kg skier skis directly down a frictionless slope angled at 12° to horizontal. Choose the positive direction of the x axis to be downhill along the slope.
A chair of weight 125 N lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of F = 35.0 N directed at an angle of 42.0 below the horizontal and the chair slides along the floor. Using Newton's laws, compute..
