Answer:
(-8.089 km, 3.945 km)
Explanation:
We need to find the x- and y-components of the following vector :
d (9 km, 26 degrees left of +y axis)
We know that the x and y component of any vector is given by :
So, x component :
y component :
So, the x and y components of the vector separated by a comma are (-8.089 km, 3.945 km). Hence, this is the required solution.
Answer:
The weight will be smaller than on Earth.
Explanation:
We call weight, to the product of the mass times the acceleration produced on this mass, due to the Universal law of gravitation.
This acceleration can be obtained applying Newton’s 2nd Law to the gravitational attractive force, as follows:
Fg = G m1m2 / (r12)2 = m1* a → a= G m2 / (r12)2 =g
If we take a planet with the same mass, but a larger size, this means that the distance, from the planet’s surface to the center, will be larger also.
As the gravitational attraction is inversely proportional to the square of the distance, this means that the acceleration caused by this force, will be smaller than on Earth.
As the mass is an universal constant, this means that the weight (as measured on a scale as the normal force) will be smaller also.
