Q1. Susan's 13.02 kg baby brother Paul sits on a mat. Susan pulls the mat across the floor using a rope that is angled 30 ^circ above the floor. The tension is the constant 31.20 N and the coefficient of friction is 0.2120.

Q2. An airplane is flying in a horizontal circle at the speed of 542 km/h. If the wings of the plane are tilted 33.0° to the horizontal, what is the radius of the circle in that the plane is flying? Suppose that the required force is provided entirely by an "aerodynamic lift" that is perpendicular to the wing surface.
