Question

A baseball has a momentum of 6.0 kg.m/s south and mass of 0.15kg. What’s the baseballs velocity?

Answer 1

v=40 m/s south

Step-by-step explanation:

Momentum

It's a physical magnitude that measures the product of the mass by the velocity of a particle. Its units in the International System is kg.m/s and the formula is

`p=m.v`

Where m is the mass and v the velocity of the particle. If we wanted to solve for v, we have

`\displaystyle v=(p)/(m)`

The baseball has a momentum of 6.0 kg.m/s south and mass of 0.15kg, thus

`\displaystyle v=(6)/(0.15)=40\ m/s`

The velocity is directed to the south
