Arocket travels vertically at a speed of 800 km/hr. the rocket is tracked through a telescope by an observer located 13 km from the launching pad. find the rate at which the angle between the telescope and the ground is increasing 3 min after lift-off. (round your answer to two decimal places.)

The rocket's altitude at time is

so that after , it will have traveled

The angle of elevation at time is such that

At the moment when , this angle is

Differentiating both sides of the equation above gives

and substituting the angle found above, and , we get

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
