A cannonball is launched with an initial velocity of 20 [m/s] and with the angle of 30 degrees (measured from the horizontal line). (a) Starting from the second Newton law, derive the equations of motion of the cannonball. (b) Compute the horizontal distance traveled by the cannonball (until it hits the ground). Neglect the air resistance forces.
