<span>In the vertical direction
there is no change of momentum.
Momentum in vertical = 1.5 * 9 = 13.5
Speed in vertical = 9 m/s
Momentum of Raven in x + momentum of falcon = initial momentum in x
=> Mx + 600*5 = 600*20
=> Mx = 600*15
=> Vx = 6000
Vy = 9
=> tanθ = 0.6 kg/9 = 0.066667</span>

<span>A lens is a piece of glass or other transparent substance with curved sides for concentrating or dispersing light rays, used singly (as in a magnifying glass) or with other lenses (as in a telescope). A binoculars, an eye, and a camera all contains a lens. A mirror does not contain a lens.</span>
Answer:
The mechanical energy of the satellite is about 12 Gigajoules
Explanation:
The total mechanical energy is the sum of the kinetic and potential energy:
While we can determine the potential energy from the given values (height above earth's surface), to calculate the kinetic energy the velocity of the satellite needs to be determined first.
The formula for orbital velocity is:
with G the gravitational constant, m_E the mass of the Earth, and r the satellite distance measured from the center of the Earth:
This velocity points in the direction of the tangent of the orbit.
Now the kinetic and total mechanical energy can be calculated:
The mechanical energy of the satellite is about 12 Gigajoules
