Astudent solving for the acceleration of an object has applied appropriate physics principles and obtained the expression a=a1 + f/m where a1 = 3.00 meter/ second2 f=12.0 kilogram. meter/second2 and m=7.00 kilogram. first which of the following is the correct step for obtaining a common denominator for the two fractions in the expression in solving for a?
(m/m times a1/1) + (1/1 times f/m)
(1/m times a1/1) + (1/m times f/m)
(m/m times a1/1) + (f/f times f/m)
(m/m times a1/1) +(m/m times f/m )
