Answer:
<h2>170km</h2>
Explanation:
If a ship sets out to sail to a point 154 km due north and an unexpected storm blows the ship to a point 72 km due east of its starting point, then the ships distance from the original destination can be gotten by finding the displacement of the ship and this can be gotten by using pythagoras theorem.
Let D be the unknown displacement
According to the theorem;
D² = 154² + 72²
D² = 23716 + 5184
D² = 28900
D = √28900
D = 170km
<em>This means that the ship must now sail a distance of 170km for it to reach its original destination.</em>

Answer:
v = 1630 m/s
T = 5.78 x 10^5 s
Explanation:
The tangential speed of the satellite can be found by requiring that the gravitational force on the satellite is equal to the centripetal force:
where
G is the gravitational constant
M=5.97 x 1024kg is the Earth's mass
m is the satellite's mass
is the Earth's radius
is the altitude of the satellite
v is the speed of the satellite
Solving for v,
And the period of the orbit is equal to the ratio between the distance covered during one revolution (the circumference of the orbit) and the speed:
So the correct answer is
v = 1630 m/s
T = 5.78 x 10^5 s
Answer:
u are falling
Explanation:
In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it.
