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 0.8 ft/s, how fast is the angle between the ladder and the ground changing when the bottom of the ladder is 6 ft from the wall? (That is, find the angle's rate of change when the bottom of the ladder is 6 ft from the wall.) rad/s wall 10 ground

A boat leaves a port traveling due east at 18 mi/hr. At the same​ time, another boat leaves the same port traveling northeast at 17 mi/hr. The angle θ of the line between the boats is measured relative to due north​ (see the figure to the​ right). What is the rate of change of this angle 30 min after the boats leave the​ port? 2 hr after the boats leave the​ port?

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 1.5 ft/s, how fast is the angle between the ladder and the ground changing when the bottom of the ladder is 6 ft from the wall? (That is, find the angle's rate of change when the bottom of the ladder is 6 ft from the wall.) rad/s wall 10 y ground
