1.	A ball is thrown upward from a 35m high bulding with velocity 30m/s .the average speed during the flight of time till it strikes the bottom of the buliding is
Answer» 6seconds Explanation:V=U+atfinal VELOCITY is EQUAL to zero -U=-gttime of FLIGHT while return t=2U/gt=2*30/10time of flight=6seconds
