Which equation is used to calculate the weight of an object on a planet?
2 answers:
W=mg
Explanation:
the weight of an object on a planet is given by the law:
where
m is the mass of the object
g is the value of the gravitational acceleration on the planet
While the mass of the object, m, depends only on the properties of the object (so, it is the same on every planet), the weight W, depends on the value of g, which is different from planet to planet, therefore the weight of an object changes if we move it to another planet.

966 mph
Explanation:
Using as convention:
- East --> positive x-direction
- North --> Positive y-direction
The x- and y- components of the initial velocity of the jet can be written as
While the components of the velocity of the wind are
So the components of the resultant velocity of the jet are
And the new speed is the magnitude of the resultant velocity:
