(In the following problems where motion as a projectile in air is involved, neglect air resistance unless otherwise stated and use g = 9.81 m/s2 or g = 32.2 ft /sec2.) A boy tosses a ball onto the roof of a house. For the launch conditions shown, determine the slant distance s to the point of impact. Also, determine the angle 8 which the velocity of the ball makes with the roof at the moment of impact. 12 5 12.5 m/s 50 4 m 1.75 m 9 m Problem 2/72
