A helicopter flies over the arctic ice pack at a constant altitude,towing an airborne 102-kg laser sensor which measures the thicknessof the ice (see the drawing). The helicopter and the sensor moveonly in the horizontal direction and have a horizontal accelerationof magnitude 2.24 m/s2. Ignoring air resistance, find the tension in the cable towing the sensor.
