44.A ball thrown with a velocity of 49m/s got the maximum range measured in the atmosphere as 225m.The decrease in range due to atmosphere is

The maximum range R =u2g = 49×499.8 = 245 m.But actual value is less than expected value because there are resistances present against the motion of the ball projected.SO because of these frictional forces of atmosphere , the maximum range is decreased.
