Read the following statements carefully and answer the questions that follow.
a. (i) Define linear momentum and write its SI unit.
b. (ii) A student says, “A heavier object always possesses more momentum than a lighter object.” Do you agree with this statement? Give one illustrative example to support your answer without performing any numerical calculation.
c. (iii) A ball of mass 2 kg moving with a speed of 3 m/s and a ball of mass 1 kg moving with a speed of 6 m/s travel in the same direction. Using appropriate calculations decide which ball has the greater momentum and explain how your answer relates to the student’s statement in part (ii).
