Steps:
Find the net force.
The vertical forces cancel out. Which leaves 1 force left; the applied force of 10000 newtons.
Use Newton’s Second Law to find the acceleration. Then plug-in the acceleration into the common kinematics equation to solve for t.

Please look at the picture/diagram I provided.

Answer:
5.40 seconds
