Answer:
= m (v – u) The rate of change of momentum = The unit of force is so chosen that the value of the constant k becomes one. So, F = ma. (b) One Newton is defined as the amount of force exerted on a body of mass 1 kg to produce an acceleration of 1 m/s2.

Explanation:
Momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton's second law of motion states that the time rate of change of momentum is equal to the force acting on the particle. See Newton's laws of motion. Momentum.
