when the effect of aerodynamic drag is included,the acceleration of a ball moving upward is given by,a(u)=-g-k(v)^2 and while moving down it is given by a(d)=-g+k(v)^2 .where k is +ve constant v is speed in m/s. if initial velocity is 30m/s when ball is thrown from ground level find maximum height h and speed v(f) upon impact with the ground . take k=0.006 SI and assume g is constant

We have given that
 as the acceleration of ball moving upwards and downwards.
In upward direction  
In downward direction
Required velocity will be
