Answer:
F = 10.86 units
Explanation:
The magnitude of a vector in terms of the magnitude of its rectangular components is given by the following formula:
F = √(Fₓ² + Fy²)
where,
F = Magnitude of the Vector = ?
Fₓ = magnitude of the x-component of vector = 8.7 units
Fy = magnitude of y component of vector = - 6.5 units
Therefore, using these values in the equation, we get:
F = √[(8.7 units)² + (- 6.5 units)²]
F = √(117.94 units²)
<u>F = 10.86 units</u>
Answer:
Explanation:
Essentially, Kinetic energy of the particle must equal the combined potential energies of earth and the moon when the object is on the moon's surface, meaning the full equation is
<h3>
</h3><h3 />
=Mass of Earth=
=Mass of Moon=
=distance from earth's center to the moon's=
=radius of moon=
After some algebra, the equation simplifies to
Plugging in the values of G, which is 
, should yield the proper answer of 2780m/s.
