Force = mass * acceleration and acceleration is in units of meters per second squared. I will assume you mean this. m/s2 Force = (1800 kg)(4 m/s2) = 7200 Newtons ----------------------
Force = mass * acceleration Force = (3000 kg)*(2 m/s^2) = 6000 Newtons ---------------------- ( that is 6000 times the force needed to push in a doorbell, on average )

(-)11,666.67 N. To calculate this, you need to use the impulse-momentum principle, whereby the change in momentum is equal to the force multiplied by the time over which the force is applied. The change in momentum here is the final speed x the mass - the initial speed x the mass. Then divide the answer by the time (six seconds) and the answer will be the force applied (in this case the answer is negative as the force is applied in the direction opposite to the direction of the truck's motion.)

The truck has a greater mass and therefore a greater amount of inertia to overcome. To accelerate a greater mass requires a greater force.
Whichever is lighter will accelerate more quickly.
The action force and reaction force occur on different objects, so they do not cancel each other out. The forward force applied by the truck is on the trailer, causing it to accelerate forward. The equal and opposite reaction force from the trailer acts on the truck, causing it to accelerate in the forward direction.

More force would be needed to stop a semi truck than a motorcycle. This is because a semi truck is heavier and has more momentum, requiring more force to slow down or stop.
force = mass x accel = 1800 x 3 = 5400 Newtons
The action and reaction forces between the truck and trailer do balance each other, but they act on different objects. The forward force from the truck on the trailer causes the trailer to accelerate forward, while the equal and opposite force from the trailer on the truck causes the truck to accelerate forward. The net result is that both the truck and trailer move forward together.
While the forces between the truck and trailer are equal in magnitude and opposite in direction, they act on different objects (truck and trailer) resulting in acceleration of the entire system. The truck exerts a force on the trailer causing it to accelerate forward, and in return, the trailer exerts an equal and opposite force on the truck. As both objects have different masses, this results in them accelerating in the direction of the larger force, which is from the truck to the trailer.
Yes, according to Newton's third law of motion, when you jump off the truck, you exert a force on the Earth, causing it to accelerate slightly towards you. However, due to the Earth's much larger mass, the acceleration of the Earth would be too small to be noticeable.
The acceleration of an object is dependent on its mass and the force applied to it. The moving truck has much more mass than the leaf, so it requires a greater force to accelerate it significantly. In this scenario, the force of the falling leaf on the truck is not enough to cause a noticeable acceleration due to the massive difference in their masses.
The force required is 70,310 newtons.
