# A marble rolling at a speed of 2 meters per second falls off the end of a 1-meter high table. How long will the marble be in the air? a. What do you know? b. What do you need to solve for? c. What equation(s) will you use? d. What is the solution to this problem?

h=1/2 g t^2 t = $\sqrt{ \frac{2h}{g} }$ =$\sqrt{ \frac{(2)(1)}{10} }$ t = 0.45 seconds
