On a car is installed a cannon to launch balls with a speed v0 = 46 m / s (with respect to the barrel of the gun). The device is mounted on the car and the car travels with velocity u = 30 m / s to the right. Ignoring air resistance: a) determine at what distance (from the point in which it is launched) the ball touches the ground b) determine the delta angle of the velocity vector of the ball with respect to an observer on the ground when it reaches the ground.
