Question

A thrower runs at a constant velocity Vconstant, he throws a projectile horizontally from a height of 2m from the ground at a velocity Vprojectile perpendicular to his constant velocity.

After throwing the projectile he continues to run at the same constant velocity Vconstant.

The projectile falls at a point A which is at a distance d = 10 m from point B where the thrower threw the projectile, and s = 6 m from the line along which he was running.

Calculate the modulus of Vprojectile, the modulus of Vconstant and the modulus of the initial velocity Vi that the projectile has with respect to the ground.
