1. The model airplane has a mass of 0.90kg and move at a constant speed on a circle that is parallel to the ground. The path of the airplane and its guideline lies in the same horizontal plane. Because the width of the plane is balanced by the lift generated by its wings. Find the tension T in the guideline. The length of the guideline is 17m for speed of 19m/s to 38m/s
