Find the current risk-free rate. How did you estimate the risk-free rate?

Please link resources and show how to do it. Thanks.

For context, this was the previous question:

1. Estimate your company's (Coca-Cola) beta.

The beta is 0.52 (based on estimations) or 0.55 (Yahoo! Finance)

For context, the question after estimating the current risk-free rate is:

2. Assume the market risk premium is 5.6%. Using the information above, calculate the cost of equity using the capital asset pricing model (CAPM).

NO NEED TO DO THIS QUESTION. JUST NEED THE ONE AT THE TOP PLEASE.
