Two projectiles are fired into the air over a lake, with the height of the first projectile given by y equals 120 plus 130 t minus 16 t squared and the height of the second projectile given by y equals negative 16 t squared plus 190 t, where y is in feet and t is in seconds. before either projectile hits the lake, determine the time interval in which the second projectile is above the first projectile.
