Answer:
In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

Answer:
4 m/sec.^2
Explanation:
Using Newton's 3rd law of motion,
s = ut + 1/2 at^2
200 = 0 × 10 + 1/2 × a × 10 × 10
200 = 0 + 50a
200 = 50a
a = 200/50
a = 4
Since, unit of acceleration is m/sec.^2.
A = 4 m/sec.^2
