The answer is: 15 . __________________________ _____ {Note: If this is a physics problem ; and the formula: "F = m*a" is for: "Force = mass * acceleration" ; be sure that the correct units are used!}. _______________________________________________________ Explanation: _______________________________ F = m * a ;
Given m = 5 ;
a = 3 ; ___________________ F = 5 * 3 = 15 . _____________________
