A girl practices her swing by hitting the ball with a tennis racket, making such that each hit sends the ball at a launch angle of 27.72 degrees. The distance to the wall is d=10.12m, and it strikes the wall with a speed that is a fraction f=0.962 of the initial speed. while it is still gaining height, (ie, it has not hit the highest point of trajectory), what is the initial velocity?
