Center of Mass and Collision question

2022 · Q143

NEETPhysicsCenter of Mass and CollisionMCQ+4 / −1

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

  1. A
    0.3 m
  2. B
    300 m
  3. C
    30 m
  4. D
    3 m

Correct answer: B

$P = mv$

$$0.3 = 5 \times {10^{ - 3}}\,v$$

$v = {{300} \over 2}$

$v = 60$ m/s

$S = v \times t$

$ = 60 \times 5$

$ = 300$ m
