If an observer sees a box moving down the z-axis at constant speed, which of the following observations about it are true? The length of the box in only the x direction is the same as if the box were at rest. The lengths of the box in the x and y directions are the same as if the box were at rest. The length of the box in only the z direction is the same as if it were at rest. The length of the box in only the y direction is the same as if the box were at rest.

Boxes A and B are at rest on a conveyor belt that is initially at rest. The belt is suddenly started in an upward direction so that slipping occurs between the belt and the boxes. Knowing that the coefficients of kinetic friction between the belt and the boxes are (μk)A = 0.8 and (μk)B = 0.82, determine the initial acceleration of each box. The initial acceleration of box A, aA, is ft/s2. The initial acceleration of box B, aB, is ft/s2.

A box which has a length, L, along each side when measured in its rest frame moves in the x direction, parallel to one face of the box. How will the dimensions of the cube appear to an observer who watches the cube move past him? The length in the x direction will be L, but it will be shorter in the y and z directions. The lengths in the y and z directions will be L, but it will be longer than L in the x direction. The length in the x direction will be less than L but the lengths in the y and z directions will be greater than L. The lengths in the y and z directions will be L, but it will be shorter than L in the x direction.

Why do observers in different reference frames disagree about the length of an object? Because moving objects are stretched by forces which make them move. Because clocks in moving frames are less accurate than clocks at rest. Because moving objects get compressed to greater density by acceleration. Because they disagree about the time of events which define the ends of the object.
