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 1

Explanation:

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

$a=a_1+\dfrac{F}{m}$ .............(!)

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 :

$a=(\dfrac{m}{m}\times a_1)+(\dfrac{1}{1}\times \dfrac{F}{m})$

Hence, this is the required solution.
