I throw a ball into the air in a movie theater. I throw it up with an initial velocity of 64 feet/sec1024ond from a balcony 10 feet high. The ceiling of the theater is 58 feet high. When will the ball hit the ceiling/
\n" ); document.write( "000000000000000000
\n" ); document.write( "Height of the ball is h(t) = -16t^2+vot+so
\n" ); document.write( "where vo is the initial velocity and so is the initial height.
\n" ); document.write( "--------------
\n" ); document.write( "Your Problem:
\n" ); document.write( "Solve 58 = -16t^2+64t+10
\n" ); document.write( "Rearrange:
\n" ); document.write( "16t^2 - 64t + 48 = 0
\n" ); document.write( "---
\n" ); document.write( "Factor:
\n" ); document.write( "16(t^2-4t + 3) = 0
\n" ); document.write( "16(t-3)(t-1) = 0
\n" ); document.write( "---
\n" ); document.write( "Smaller positive solution:
\n" ); document.write( "t = 1 second
\n" ); document.write( "The ball will hit the ceiling in one second.
