I believe the answer is true
Answer:
24 Newtons
Explanation:
The force exerted in the middle cube needs to be enough to move the middle cube and the right cube with an acceleration of 2 m/s2.
The mass of those two cubes combined is 6 + 6 = 12 kg
So, using the following equation, we can find the force:
Force = mass * acceleration
Force = 12 * 2
Force = 24 Newtons
here we can use energy conservation
like initial kinetic + potential energy is always conserved and it will be same at all points
so we can say
now we can plug in all the given values in it
now divide whole equation by mass "m"
so final speed will be 65.96 m/s

From Newton's second law, F= ma
F = 2000 kg x 15 m/s^2 = 30000 N
