Calculate the components of the velocity vector as a function of time. Express your answers in terms of v0x , v0y , β , γ , and α . Enter your answers separated by a comma.
a) vx(t) = v0x cos(α t) , vy(t) = v0y sin(β t)
b) vx(t) = v0x sin(γ t) , vy(t) = v0y cos(α t)
c) vx(t) = v0x sin(α t) , vy(t) = v0y cos(γ t)
d) vx(t) = v0x cos(β t) , vy(t) = v0y sin(α t)
