When an airplane leaves the runway, its angle of climb is 11 ◦ and its speed is 278 feet per second. How long will it take the plane to climb to an altitude of 14816 feet? Answer in units of sec
|dw:1320612547227:dw| I think this will help you figure it out on your own. Consider using the sine function to set up a problem and solve for 14,816 ft. Good luck.
vertical component of velocity = 278sin11 ft/sec to find time to climb to 14816 : 278 sin11 = 14816 / t t = 14816 / 278 sin 11
so what's the answer in seconds?
work out the last line t = 14816 / 278 * sin 11
