What is the trajectory of a thrown body?
How does it depend on the values of the velocity projections?
Let a body was thrown with a velocity, having horizontal projection vx and vertical projection vy . Let X0 and Y0 are respectively horizontal and vertical coordinates of initial point of movement.
The movement of the body described as follows:

        X=X0+vx*t,

        Y=Y0+vy*t-gt2/2,

Select some values and parameters, throw the body, measure its position in some time t and verify accordance of experimental results and calculated values.
Initial Values of Parameters
Initial horizontal position (X0) 0 m
Initial vertical position (Y0) 90 m
Initial horizontal velocity projection (vx) 10 m/sec
Initial vertical velocity projection (vy) 0 m/sec
Gravitational constant (g) 9.8 m/sec2
