gosh dats cool i got it right yeah.........


I would surely tell you....


C assume the initial speed to be 'u'


we got a distace of 8 m to travel before the net which is 2.24 m high. since the original height at which the ball was hit was 3 m, so the difference in height is 3-2.24=.76m. Using horizontal projectile formula i.e. range = u(2h/g)1/2


we get 8=u[(2 x .76)/9.8]1/2


: u=8[9.8/(2 x .76)]1/2


: u=20.32m/s.


Dats all.
