Answer:
- Newton's first law applies. An object at rest will stay that way until a force is applied.
- Any amount of effort can be applied to any amount of mass (in the ideal case). The question is not sufficiently specific.
Explanation:
A force is required to move an object because the object will stay at rest until a force is applied.

The effort required to lift or push two masses instead of one depends on the desired effect. For the same kinetic energy, no more effort is required. For the same momentum, half the effort is required for two masses. For the same velocity, double the effort is required.
The answer to your question is body weight,<span> </span>body heat and muscle mass<span>.

Convergent- the plates were converging(pushing) together causing one to push under another.
The deceleration of the car is 3 m/s².
<u>Explanation:</u>
So the initial velocity of the car is given as 12 m/s. As the car is said to slow down and then it stops after 4 seconds, so the final velocity is zero.
We know that the acceleration acting on any object to stop the motion of that object is termed as deceleration or negative acceleration.
This is because, acceleration is the ratio of change in velocity to time taken for that change in velocity.
So., 
So the deceleration of the car is 3 m/s².
