Answer:
Approximate height of the building is 23213 meters.
Explanation:
Let the height of the building be represented by h.
0.02 radians = 0.02 ×
= 0.02 x (180/)
0.02 radians = 1.146°
10.5 km = 10500 m
Applying the trigonometric function, we have;
Tan θ =
So that,
Tan 1.146° =
⇒ h = Tan 1.146° x 10500
= 2.21074 x 10500
= 23212.77
h = 23213 m
The approximate height of the building is 23213 m.
Answer:
The baseball was falling during 1.733 seconds.
Explanation:
The baseball experimented a free fall, which is a particular case of uniformly accelerated motion, in which object is accelerated by gravity. In this case, we need to determine the time spent by the ball before hitting the ground (), measured in seconds, which is determined by the following kinematic formula:
(1)
Where:
,
- Initial and final speeds of the baseball, measured in meters per second.
- Gravitational acceleration, measured in meters per square second.
If we know that ,
and
, then the time spent by the baseball is:
The baseball was falling during 1.733 seconds.
