Acube has a density of 1800 kg/m3 while at rest in the laboratory. what is the cube's density as measured by an experimenter in the laboratory as the cube moves through the laboratory at 91.0 % of the speed of light in a direction perpendicular to one of its faces? you may want to review (pages 1040 - 1043) .

4341.44763 kg/m³

Explanation:

= Actual density of cube = 1800 kg/m³

= Density change due to motion

v = Velocity of cube = 0.91c

c = Speed of light =

Relativistic density is given by

The cube's density as measured by an experimenter in the laboratory is 4341.44763 kg/m³

not moving. pos accel,
