Question

A steel ball whose mass is 2.0 kg is rolling at a rate of 2.8 m/s. What is its momentum? (Round to the nearest tenth).

Answer 1

Explanation:

P = M * v

P = 2 * 2.8

p = 5.6 kgm/s

Answer 2

Answer: P= 5.6 kg m/s

Explanation:

• Momentum of a body is the product of its mass and its velocity.
• It is denoted by letter P.
• P= m*V

         Given, m=2 kg and V=2.8 m/s.

        P= 2*2.8

    ∴  P= 5.6 kg m/s.

• Hence, the required momentum of the body is 5.6 kg m/s.
