Ajet with mass m = 6 × 104 kg jet accelerates down the runway for takeoff at 1.9 m/s2.1) what is the net horizontal force on the airplane as it accelerates for takeoff?

Net horizontal force on the airplane as it accelerates for takeoff = 1140 kN

Explanation:

  The force on any body can be defined as product of mass and acceleration

That is Force, F = ma

  In this case mass of jet, m = and acceleration of jet, a = .

   Substituting in the above equation we have

              Force, F = =

So, net horizontal force on the airplane as it accelerates for takeoff = 1140 kN

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
