8. What must be the mass of a model rocket engine be in grams to develop an acceleration of 520 m/s2 when subjected to a force of 11.2 N? Please include the equation, it would really help me out, thanks so much!

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
