An airplane of mi 1100 kg is pulling two gliders the first

An airplane of mi = 1100 kg is pulling two gliders, the first or mass ni; = 280 kg and the second of mass mj = 320 kg. down the runway with an acceleration of 1.5 m/s\". Neglecting the mass of the two ropes and any frictional forces, determine the magnitude of the tension force in the first rope. a. 0.42 kN. b. 1.08 kN. c. 0.48 kN. d. 0.90 kN. c. 2.6 kN. d. 0.90 kN. e. 2.6 kN

Solution

The tension is: (m2+m3)*a = (320+280)*1.5 = .9kN
