Question

name the physical quantity whosr si unit is newton second and kg mitres per second

Answer 1

The newton second (also newton-second, symbol N s or N. s) is the derived SI unit of impulse. It is dimensionally equivalent to the momentum unit kilogram metre per second (kg. m/s).

Answer 2

Newton's Second Law states that force equals mass multiplied by acceleration. The unit of force is the newton (N), and mass has the SI unit kilogram (kg). One newton equals one kilogram metre per second squared.
