Question

Which has a large momentum :
(i) a body of mass 20 kg moving with 30 m/s.
(ii) a body of mass 15 kg moving with 35 m/s?

Answer 1

Body one has larger momentum than body two.

Explanation:

p = mv

p is momentum, m is mass and v is velocity

(i) mass is 20 kg and velocity is 30 ms-1.

So momentum p1 = 20 * 30 = 600 kgm/s

(ii) mass is 15 kg and velocity is 35 ms-1.

So momentum p2 = 15 * 35 = 525 kgm/s

p1 is 600 while p2 is 525. So, body one has larger momentum than body two.
