Answer:
=(5.7 x
i - 2.24 x
j) kgm/s
Explanation:
Due to earths gravity, force on asteroid is given by:
r^
Plugging in the values, we have
F= [(6.67x)(1500)(5.97 x
)(8x
i + 9x
j)] / ((8x
)² + (9x
)²
F= 2736 i^ + 3078 j^
In order find the final momentum of the Asteroid, apply impulse momentum theorem
=
+ FΔt
= 1500(3.5 x
i - 1.8x
j) + (2736i + 3078j)(1.5x
)
=(5.7 x
i- 2.24 x
j)kgm/s
Missing question: "how much work is done by the teacher?" (found on internet)
Solution:
The work done to move the desk across the floor is equal to
where F is the horizontal force applied to move the desk, and d is the distance covered by the desk. If we use F=20 N and d=5 m, we find the work done:

The north celestial pole (and also the south) are described as two imaginary points that project on the axis of rotation of the earth, indefinitely towards space and that intersects with the celestial sphere (Remember that the earth has a slight inclination with respect to to its axis of rotation). The north and south celestial poles are directly above the head of someone located at the north or south pole of the earth.
Correct Answer is A.
