Snowboarding in the half-pipe. 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 ft above the edge of the half-pipe. His speed v ( t ) , in miles per hour, upon reentering the pipe can be approximately 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?

Let a = (-1, -2, -3) and 6 = (-4, 0, 1).
Find the component of b onto a.
Forces of 9 pounds and 15 pounds act on each other with an angle of 72°.
The magnitude of the resultant force
The resultant force has an angle of

* with the 9 pound force.
The resultant force has an angle of
with the 15 pound force.
It is best to calculate each angle separately and check by seeing if they add to 72°.
