A particle is thrown with a speed u at an angle (theta) with the horizontal.when the particle makes an angle (phi) with the horizontal,its speed changes to v: Ans. is v=ucos(theta)sec(phi)

In first case, it angle is theta then 
Horizontal speed =ucos theta .
since their is no any force , acceleration (a=0) is constant in horizontal direction.
In second case , horizontal speed=vcos phi
Then ,
              Ucos theta=vcos phi
                 V=ucos theta /cos phi
