Shaun White, "The Flying Tomato," won a gold medal in the 2010 Winter Olympics for snowboarding in the half-pipe. He soared an unprecedented \(25 \mathrm{ft}\) above the edge of the half-pipe. His speed \(v(t)\), in miles per hour, upon reentering the pipe can be approximated by \(v(t)=10.9 t,\) where \(t\) is the number of seconds for which he was airborne. White was airborne for 2.5 sec. (Source: "White Rides to Repeat in Halfpipe, Lago Takes Bronze," Associated Press, \(2 / 18 / 2010 .\) ) How fast was he going when he reentered the half- pipe?

The distance \(s(t),\) in feet, traveled by a body falling freely from rest in \(t\) seconds is approximated by \(s(t)=16 t^{2}\) On April \(6,2006,\) pro skateboarder Danny Way smashed the world record for the "bomb drop" by free-falling \(28 \mathrm{ft}\) from the Fender Stratocaster guitar atop the Hard Rock Hotel \& Casino in Las Vegas onto a ramp below. (Source: www.skateboardingmagazine.com.) How long did it take until he hit the ramp?
