Answer:
An object of mass 20 kg is moving with a velocity of 10 m / s. Its momentum will be: A. 2000 kg · m / s, B. 200 kg · m / s, C. 2 kg · m / s, D. 20 kg · m / s An object of mass 20 kg is moving with a velocity of 10 m / s. Its momentum will be: A. 2000 kg · m / s, B. 200 kg · m / s, C. 2 kg · m / s, and D. 20 kg · m / s.
Step-by-step explanation:
The correct option is (B) 200 kg.m/s
Given,
Mass of the body = 20 kg
Velocity of the body = 10 m/s
We know,
The momentum of a body is given by the product of the mass of the body and velocity.
