The distance covered by a body of mass 5 ~g having linear momentum 0.3 ~kg ~m / s in 5 ~s is:

Options

  1. A300 ~m
  2. B30 ~m
  3. C3 ~m
  4. D0.3 ~m

Correct answer

A. 300 ~m

Step-by-step solution

Given, aligned m=5 ~g & =0.005 ~kg , P =m v & =0.3 ~kg ~m / s , and t & =5 ~s , aligned (where, symbols have their usual meanings.) P =m v=0.3 Hence, V = 0.3 m = 0.3 0.005 =60 ~m / s Hence, the distance covered = speed time =60 5=300 ~m
