Using newton's second law
F= ma
100= {tex}m(v—u)\over t{/tex}
100 = {tex}m( 20—0)\over 5{/tex}
500= 20m
{tex}500\over 20{/tex} = m
25kg = m

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of its speed and direction of motion.

A dimensionless physical constant, sometimes called a fundamental physical constant, is a physical constant that is dimensionless. It has no units attached and has a numerical value that is independent of the system of units used

Newton's second law is the real law of motion in the sense that the firest and third law of motion can be derived from the 2nd law of motion.
From Newton’s 2nd law, F = ma
If F = 0, then a = 0
This means that if no force is applied on the body, its acceleration will be zero. If the body is at rest, it will remain in the state of rest and if it is moving, it will remain moving in the same direction with the same speed. Thus, a body not acted upon by an external force, does not change its state of rest or motion. This is the statement of Newton’s first law of motion.
Also the 3 rd law of motion can be derived from the 2nd law.
Consider an isolated system of two bodies A and B. An isolated system is such that no force acts on the system.
This is the Newton’s third law of motion for a body exerting some force on another.
Thus, Newton’s 2 nd law of motion is the most basic law of motion.

Inertia is an inherent property of the object due to which object is unable to change the state of rest or state of motion until and unless an external force is applied on it.
