Commercial airplanes are sometimes pushed out of the passenger loading area by a tractor. An 1800-kg tractor exerts a force of 1.75*10^4N backward on the pavement, and the system experiences forces resisting motion that total 2400 N. If the acceleration is 0.150 m/s2, what is the mass of the airplane?

1 x 10^5 kg

Explanation:

mass of tractor, m = 1800 kg

F = 1.75 x 10^4 N

f = 2400 N

a = 0.150 m/s^2

Fnet = F - f = 1.75 x 10^4 - 2400 = 15100 N

Fnet = mass of airplane x acceleration

mas of airplane = 15100 / 0.15 = 1 x 10^5 kg
