A ball is thrown vertically upwards from the top of a tower with an initial velocity of 19.6 ms-1The ball reaches the ground after 5 s. Calculate :(i) the height of the tower, (ii) the velocity of ballon reaching the ground. Take g = 9.8 m s2.Ans. (i) 24.5 m (ii) 29.4 m s-1​

Answer»

-step explanation:The velocity of the BALL on REACHING the GROUND is 29.4 m/s. Time taken by ball to reach ground 't' = 5 sec. So, ⇒ t = 2 sec. it means time taken to reach max.. ok
