document.write( "Question 152047: A circus performer is juggling clubs while standing on stilts. He releases a club from a point 8ft above the ground with the initial vertical velocity of 10 ft per second. \r
\n" ); document.write( "\n" ); document.write( "The vertical motion mode is h = -16t2(It's t to the second power) + vt + s where he is the height of an object in feet, t is the time seconds, v is the initial vertical velocity in feet per second, and s is the initial height in feet. \r
\n" ); document.write( "\n" ); document.write( "a) Write an equation in function notation that models the height (in feet) of the club as a function of time (in seconds).\r

You can put this solution on YOUR website!
You are given the equation
\n" ); document.write( "\"h+=+-16t%5E2+%2B+v%5B0%5Dt+%2B+s%5B0%5D\"
\n" ); document.write( "You are told the initial velocity is 10 feet/sec so \"v%5B0%5D+=+10\"
\n" ); document.write( "You are told the initial position is 8 feet above the grouns. so \"s%5B0%5D+=+10\"\r
\n" ); document.write( "\n" ); document.write( "Substitute that info into the equation to get
\n" ); document.write( "\"h+=+-16t%5E2+%2B+10t+%2B+8+\"\r
\n" ); document.write( "\n" ); document.write( "Plug in values for t from 0.1 through 1.5 and solve for h. You'll need to grind that out by hand., Just pick a few values for t and solve for h using the eqaution we just made.\r
\n" ); document.write( "\n" ); document.write( "graph the equation
\n" ); document.write( "\"graph%28400%2C400%2C+-1%2C3%2C+-1%2C+11%2C+-16x%5E2+%2B10x+%2B8%29\"
\n" ); document.write( "height is the y axis, time is the x axis.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "To find the max height, look at the plot. Mark that point and then drop down to find the time and across to find the height\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "To find when it hits the round, set h = 0 and solve for t. Or look at the plot and find the time when the graph touches the x axis
