A 10 m ladder leans against a vertical wall and the bottom of the ladder slides away from the wall at a rate of 0.3 meters per second. How fast is the top ladder sliding down the wall? (a) when the bottom of the ladder is 4 m from the wall? the height of the top of the ladder is changing at a rate of = m/sec  this means the top of the ladder is sliding down at a rate of = m/sec  (b) when the bottom of the ladder is 8 m from the wall?  the height of the top of the ladder is changing at a rate of = m/sec  this means the top of the ladder is sliding down at a rate of=  m/sec what do you notice from the previous answers?

(a) when the bottom of the ladder is 4 m from the wall?

the height of the top of the ladder is changing at a rate of = m/sec 

this means the top of the ladder is sliding down at a rate of = m/sec 

(b) when the bottom of the ladder is 8 m from the wall? 

the height of the top of the ladder is changing at a rate of = m/sec 

this means the top of the ladder is sliding down at a rate of=  m/sec
