Question

A metallic sphere having mass 2 kg is moving with a velocity of 10 m/s. The momentum of the sphere in kg metre/ sec. will be-
(A) 1/5
(B) 5
(C) 12
(D) 20

Answer 1

Answer:

20 kg m/s

Explanation:

In this question,

A metallic sphere having mass 2 Kg is moving with a velocity of 10 m/s.

We need to find the momentum of the sphere

We know that momentum is given by

P = Mass × Velocity

Here, Mass = 2 k.g

          Velocity = 10m/s

Putting the values we get,

P = 2 × 10

P = 20 kg metre/sec.

Hence the momentum of the sphere is 20 k.g meter/sec.
