a gun is fired straight upward. the bullet leaves the gun at 100 feet per second (time t=0) after 2 seconds the velocity of the bullet is 36 feet per second there is a linear equation that gives the velocity v in terms of the time t.
\n" ); document.write( "-----------------------
\n" ); document.write( "You have two points relating time and velocity:
\n" ); document.write( "(0,100) and (2,36)
\n" ); document.write( "slope = (36-100)/(2-0) = -32
\n" ); document.write( "---
\n" ); document.write( "intercept = 100
\n" ); document.write( "---------------------
\n" ); document.write( "Equation:
\n" ); document.write( "velocity = -32(time) + 100
\n" ); document.write( "-------------
\n" ); document.write( "Find the velocity after 3 seconds.
\n" ); document.write( "v(3) = -32(3) + 100
\n" ); document.write( "v(3) = -96+100
\n" ); document.write( "v(3) = 4 ft/sec
