A	864.36 grams
B	9 grams
C	about 0.1 grams
D	there is not enough information to answer this question

Explanation:

Detailed explanation-1: -According to Newton’s second law of motion, Force is the product of mass and accleration. And we know that weight is the force with which the body is attracted towards the earth. The unit kg m/s² can also be written as N. Hence the required force of gravity with which the hammer is attracted towards the earth is 88.
