. An airplane sets an airspeed of 350 km/h at [N20E], and there is a wind blowing due East at 70 km/h. What is the ground speed of the airplane, both magnitude and number of degrees (clockwise) from due North? .Three forces with magnitudes 15N, 10N, and 9N are in equilibrium. Find the angle between the 10M and 9N force. (Remember how we arrange vectors when we want to talk about the angle between them). . An air ambulance is travelling from CityA to City B. City B is located 90 km [N15E] of City A. If the wind is blowing from the North with a velocity of 50 km/h, and the plane's air speed is 400 km/h, what direction must the pilot y to make it to City B? . A mirrorball with a mass of 40 kg is suspended from the ceiling by two lengths of rope that make angles of 50 and 29 respectively with the ceiling. Find the tension in each rope
