Answer to Question #2260 in Mechanics | Relativity for Ryan Rigby
x = V0x t = V0 cosα*t
y = V0y t-g t2/2 = V0 sinα*t - g t2/2
Vx = V0x = V0 cosα
Vy = V0y - gt = V0 sinα - gt
V = √(Vx2 + Vy2 )
As we see Vy decrease with time. So the magnitude of velocity also decrease. Velocity is maximum at t=0 and equals V0.
