6- A pitcher has the ability to throw a 0.14-kg baseball with the same momentum
of a 3-g bullet moving at speed of 3,000 m/s. What is baseball's speed?

Answer 1

This question can be solved simply by using the formula of the momentum, involving speed and mass.

The speed of the baseball is "64.28 m/s".

It is given that the momentum of the baseball must be equal to the momentum of the bullet. Hence, we will compare both:

$Momentum\ of\ Baseball = Momentum\ of\ Bullet\\m_1v_1=m_2v_2$

where,

m₁ = mass of baseball = 0.14 kg

m₂ = mass of bullet = 3 g = 0.003 kg

v₁ = speed of baseball = ?

v₁ = speed of bullet = 3000 m/s

Therefore,

$(0.14\ kg)v_1=(0.003\ kg)(3000\ m/s)\\\\v_1= \frac{9\ kgm/s}{0.14\ kg}$

v₁ = 64.28 m/s
