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 1.1 ft/s,

pishuonlain [190]

let:
X = the distance of the bottom of the ladder from the wall at any time
dX/dt = rate of travel of the bottom of the ladder = 1.1 ft/sec
A = the angle of the ladder with the ground at anytime
dA/dt = rate of change of the angle in radians per second

X = 10 cos A

dX/dt= -10 sin A dA/dt = 1.1

dA/dt = -1.1/(10 sinA)

When X = 6; cosA = 6/10; sinA = 8/10

Therefore:

dA/dt = -1.1/(10 x 0.8) = -0.1375 radiant per second.
