Amodel jet is fired up in the air from a 16-foot platform with an initial upward velocity of 52 feet per second. the height of the jet above ground after t seconds is given by the equation 2003-18-06-00-00_files/i003.jpg, where h is the height of the jet in feet and t is the time in seconds since it is launched. approximately how long does it take the jet to reach its highest point?
a.0.3 seconds
b.1.6 seconds
c.3.3 seconds
d.6.5 seconds

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:
