Please answer and explain the following questions about Force and Motion. Thanks

1. A cannon fires projectiles at a fixed speed but with variable angle. The range of the cannon is L when it fires at an angle 30 above the horizontal. What is the maximum range of the cannon? You can ignore air resistance. A L B. V3L C. V2L D.2L s AL 2. A particle moves on a 2D surface under the action of a force, which always points to the right side and perpendicular to the particle's velocity. The magnitude of the force is constant. From the observer looking from above, A. the particle moves in an ellipse with constant speed. B. the particle moves in a uniform circular motion. C. the particle moves in a circular with a varying speed. D. the particle moves in a parabola with varying speed. E. the particle could move in circular or elliptical trajectory depending on its speed
