The construction company outside is raising a 200 foot steel beam using a crane. At the start, it's laying flat on the ground. The bottom of the beam will always remain in the same exact spot on the ground, but the top of the beam will be pushed up until it's standing straight up. During this process, there is an angle between the beam and the ground that is increasing at a rate of .8 radians per minute. When the height of the beam is 100 feet (where height refers to the distance between the top of the beam and the ground), at what rate is this height increasing?

The construction company outside is raising a 200 foot steel beam using a crane. At the start, it's laying flat on
the ground. The bottom of the beam will always remain in the same exact spot on the ground, but the top of the
beam will be pushed up until it's standing straight up. During this process, there is an angle between the beam
and the ground that is increasing at a rate of .8 radians per minute. When the height of the beam is 100 feet
(where height refers to the distance between the top of the beam and the ground), at what rate is this height
increasing?
