Question

A 2400kg airplane is pulling two gliders, the first of mass 330kg and the second of mass 280kg, down the runway with an acceleration of 1.9m/s2 (Figure below). Neglecting the mass of the two ropes and any frictional forces.

(a). Determine the horizontal thrust F of the plane's propeller.

(b). Determine the tension force T1in the first rope.

(c). Determine the tension force T2in the second rope.

(d). Determine the net force Fneton the first glider.

Determine the tension force T2in the second rope. (d). Determine the net force Fneton the first glider.

Explanation / Answer

a)
F = ma = (2400 +330+280) *1.9 = 5719 N.

b)

T1 = (330+280) *1.9 = 1159
c)
T2 = 280 *1.9 = 532

d}
330 *1.9 =627 N
