Question

A student 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?

a. (m/m times a1/1) + (1/1 times F/m)
b. (1/m times a1/1) + (1/m times F/m)
c. (m/m times a1/1) + (F/F times F/m)
d. (m/m times a1/1) +(m/m times F/m )

Please choose the correct answer choice I put the word times to repersent the dot of multiplcation .

Answer 2

Step-by-step explanation:

A student solving for the acceleration of an object has applied appropriate physics principles and obtained the expression as :

`a=a_1+(F)/(m)` .............(!)

Where

`a_1=3\ m/s^2`

`F=12\ kg-m/s^2`

m = 7 kg

We need to find the value of a from equation (1). On solving we get :

`a=((m)/(m)* a_1)+((1)/(1)* (F)/(m))`

Hence, this is the required solution.
