Final answer:
To make k the subject of the equation k = km/2, you can multiply both sides by 2 and rearrange the equation to isolate k.
Depending on the value of m, the solution for k will be either 0 or 2 - m.
Step-by-step explanation:
To make k the subject of the equation k = km/2, we can start by multiplying both sides of the equation by 2 to eliminate the denominator:
2k = km
Next, we can rearrange the equation to isolate k on one side:
2k - km = 0
Factoring out k from the left side yields:
k(2 - m) = 0
Finally, we can solve for k by setting either factor equal to zero:
k = 0 or 2 - m = 0
Depending on the value of m, the solution for k will be either 0 or 2 - m.
