The freefall function to calculate velocity, v, of an object that begins at rest and falls for distance d is v(d)=2gd−−−√ , where g is the acceleration due to gravity.

The Storm Runner roller coaster at Hershey Park drops 55 m. Use the freefall function to calculate to the nearest tenth its velocity at the end of the freefall. Use g = 9.8 m/s2.

Enter your answer in the box.
