Answer:
The answer is below
Explanation:
The maximum height (h) of a projectile with an initial velocity of u, acceleration due to gravity g and at an angle θ with the horizontal is given as:
Given that the two projectile has the same height.
Explanation:
Orbital period = 2 x 10⁶s
Total radius = 2.5 x 10¹²m
Unknown:
Tangential speed of the satellite = ?
Solution:
The tangential speed simply expresses the rate at which the distance moves around its orbit with time.
Since the orbit is taken to be circular;
Tangential speed = 
r is the radius
t is the time or orbital radius
Tangential speed = ![\frac{2 x 3.14 x 2.5 x 10¹²}{2 x10[tex]^{6}](https://tex.z-dn.net/?f=%5Cfrac%7B2%20x%203.14%20x%202.5%20x%2010%C2%B9%C2%B2%7D%7B2%20x10%5Btex%5D%5E%7B6%7D)

Tangential speed = 7.85 x 10⁶m/s

Explanation:
Answer:
233.1 miles per hours
Explanation:
Speed: This is defined as the ratio of distance to time. The S.I unit of speed is m/s. speed is a vector quantity because it can only be represented by magnitude only. Mathematically, speed can be expressed as,
S = d/t ....................... Equation 1
Where S = speed of the runner, d = distance covered, t = time.
Given: d = 100 meter , t = 9.580 seconds
Conversion:
If, 1 meter = 0.00062 miles
Then, 100 meters = (0.00062×100) miles = 0.62 miles.
Also
If, 3600 s = 1 h
Then, 9.580 s = (1×9.580)/3600 = 0.00266 hours.
Substitute into equation 1
S = 0.62/0.00266
S = 233.1 miles per hours.
Hence the runner speed is 233.1 miles per hours
I hope this helps. Your answer is D
