A ladder 10 ft long rests against a vertical wall. If the bottom of the ladder slides away from the wall at a rate of 1.4 ft/s, how fast is the angle between the ladder and the ground changing when the bottom of the ladder is 8 ft from the wall? (That is, find the angle's rate of change when the bottom of the ladder is 8 ft from the wall.)

A ladder is leaning against a vertical wall, and both ends of
the ladder are at the point of slipping. The coefficient of
friction between the ladder and the horizontal surface is μ1 =
