    Robert is jamming out on the air guitar and leaps a meter into the air on a hot riff. How long does it take before he lands?

    Thank you.

    I don't have an attempt. I'm not even sure what formula to use, or how to solve this equation. I do know that acceleration is 9.8 m/s^2. But I'm not sure how to solve this. Thank you.
