Q3: A cannonball with an initial height of 1.5 meter above the ground is fired from a cannon at an angle of θ above the horizontal and with initial velocity of 40 m/s. The cannonball travels a horizontal distance of 30 meters and passes over a 14 meter high castle wall. Find the initial firing angle θ How much time it takes for the ball to pass over the castle wall ?. Find the velocity (magnitude and direction ) if the cannonball as it over the castle wall
