**drwls**, Tuesday, February 22, 2011 at 1:25pmThe horizontal velocity component must be Vx = 40/5 = 8 m/s

The initial vertical component Voy must satisfy this equation

Voy*T - (g/2)T^2 = -50

where T = 5 s, so

Voy = 14.5 m/s

Speed when thrown = sqrt(Voy^2 + Vx^2]

= sqrt[(14.5)^2 + 8^

= 16.6 m/s

The ratio Voy/Vx is the tangent of the launch angle
