document.write( "Question 335703: I need help on this problem:
\n" ); document.write( "An object's altitude, in meters, is given by the polynomial h + vt - 9.8t2, where h is the height in meters from which the launch occurs, v is the initial upward speed in meters per second, and t is the number of seconds for which the rocket is airborne. A pebble is shot upward from the top of a building 190 meters tall. If the initial speed is 40 meters per second, how high above the ground will the pebble be after 2 seconds? Round results to the nearest tenth of a meter. \n" ); document.write( "
