Answer:
25.71486 seconds
Explanation:
t = Time taken
u = Initial velocity = 60 mph
v = Final velocity = 80 mph
s = Displacement = 0.5 mile
a = Acceleration
Converting to m/s
From equation of motion
Time taken is 25.71486 seconds

Answer:
vertical component = 9.7m/s
Explanation:
Vy= (23)sin25 = 9.7m/s
The star with apparent magnitude 2 is more brighter than 7.
To find the answer, we have to know about apparent magnitude.
<h3>What is apparent magnitude?</h3>
- 100 times as luminous as a star with an apparent brightness of 7 is a star with a magnitude of 2.
- The apparent magnitude of bigger stars is always smaller.
- The brightest star in the night sky is Sirius.
- The brightness of a star or other celestial object perceived from Earth is measured in apparent magnitude (m).
- The apparent magnitude of an object is determined by its inherent luminosity, its distance from Earth, and any light extinction brought on by interstellar dust in the path of the observer's line of sight.
Thus, we can conclude that, the star with apparent magnitude 2 is more brighter than 7.
