The engine of a jet aircraft applies a thrown force of 10^5 ~N during take off and causes the plane to attain a velocity of 1 ~km / s in 10 s . The mass of the plane is

Options

  1. A10^2 ~kg
  2. B10^3 ~kg
  3. C10^4 ~kg
  4. D10^5 ~kg

Correct answer

B. 10^3 ~kg

Step-by-step solution

Acceleration produced in jet = Change in velocity Time a= (10^3-0 ) 10 Mass = Force Acceleration = 10^5 10^2 =10^3 ~kg
