Question

The 1800 kg tractor exerts a force of 1.95 104 N backward on the pavement, and the system experiences forces resisting motion that total 2400 N. If the acceleration is 0.230 m/s2, what is the mass of the airplane in kilograms?

Answer 1

Answer:72547.82 kg

Step-by-step explanation:

Given

Mass of tractor is
`(M) 1800 kg`

Force exerted
`(F)=1.95* 10^4 N`

Resisting Force
`(f_R)=2400 N`

acceleration of system(a)
`=0.23 m/s^2`

Let mass of airplane be m

so

`F-f_r=(M+m)a`

`1.95* 10^4-2400=(1800+m)\cdot 0.23`

`19500-2400=(1800+m)\cdot 0.23`

`1800+m=(17,100)/(0.23)`

m=74347.82-1800=72547.82 kg
