Ahelicopter flies over the arctic ice pack at a constant altitude, towing an airborne 129-kg laser sensor that measures the thickness of the ice (see the drawing). the helicopter and the sensor both move only in the horizontal direction and have a horizontal acceleration of magnitude 2.84 m/s2 . ignoring air resistance, find the tension in the cable towing the sensor.

1317.52 Newton

Explanation:

Mass of sensor = m = 129 kg

Acceleration of the sensor = a = 2.84 m/s²

g = Acceleration due to gravity = 9.81 m/s²

= Force on the laser sensor due to motion = 129×2.84 = 366.36 N

= Force due to gravity on the laser = mg = 129×9.81 = 1265.49 N

Tension in the cable

∴ The tension in the cable towing the sensor is 1317.52 Newton

the right answer is 0.3 meters per second
