The velocity ds/dt (in meters/second) of a projectile is given by
\n" ); document.write( "ds/dt=-9.8t+16
\n" ); document.write( "Find the displacement s of the object after 4 seconds if the initial displacement is 48 m.
\n" ); document.write( "-----------------
\n" ); document.write( "s = the integral of ds/dt
\n" ); document.write( "s = -4.9t^2 + 16t + C
\n" ); document.write( "C = 48 m, the initial displacement
\n" ); document.write( "------------------
\n" ); document.write( "s(t) = -4.9t^2 + 16t + 48
\n" ); document.write( "s(4) = -4.9*16 + 64 + 48
\n" ); document.write( "s(4) = 33.6 meters\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
