a projectile shot at an angle of 60 degrees above the horizontal strikes a building 80 ft away at a point 48 ft above the point of projection (a) find the velocity of projection. (b) find the magnitude and direction of the velocity of the projectile when it strikes the building.
please help me,,,

(a) Write two independent equations for the time of flight T, based upon (1) the initial vertical component and (2) the horizontal component of initial velocity, Vo. Set the two times equal to eliminate T, and then solve for Vo
(b) Vx = Vo cos60
Vy (at impact) = Vo*sin60 -g*T
Fot T, use 80 ft/(Vo*cos60)
(b) Vx = Vo cos60
Vy (at impact) = Vo*sin60 -g*T
Fot T, use 80 ft/(Vo*cos60)
