Question

A baseball with a mass of 145 g is thrown at a velocity of 42.3 m/s. Express its momentum in the appropriate SI unit

Answer 1

6.1335 Kg.m/s

Step-by-step explanation:

Momentum, p=mv where m is the mass of the object in Kg and v is the velocity of the object expressed in m/s

Given information

mass, m=145 g=145/1000=0.145 Kg

velocity, v=42.3 m/s

Therefore, substituting the given values we obtain

Momentum=0.145*42.3=6.1335 Kg.m/s
