Answer:
0.0031792338 rad/s
Explanation:
= Angle of elevation
y = Height of balloon
Using trigonometry
Differentiating with respect to t we get
Now, with the base at 200 ft and height at 2500 ft
The hypotenuse is
Now y = 2500 ft
The angle is changing at 0.0031792338 rad/s
Answer:
9.8 secs
Explanation:
the ball is in the air so it takes 9.8 secs to get to the ground
They will rise to the 2nd layer of the atmosphere where the temperature decreases by a lot and then they will blow up
