Answer:Newtons Second Law tells us that F=ma . From this we can infer that a= m/f. Since F is directly proportional to a , quadrupling F will also quadruple a . And since m is inversely proportional to a , halving m will double a . Were quadrupling a and then doubling a , which means that, ultimately, multiplying a by eight.
