This is for my astronomy class.  I don't even know where to start: using the relationship “force equals mass times acceleration,” write an answer the following question: if an object with mass X grams is being accelerated at Z centimeters per second squared, then how much force is being exerted on the object?  Show your calculations.

i just need Explanaion about the table no answer needed
