A baseball has a mass of 0.145 kg. A professional pitcher throws a baseball 67 mi/h, which is 30.0 m/s. What is the magnitude of

Kamila [148]

The concept of momentum tells us that it is equivalent to the product between the mass and the velocity of the object, that is to say that in general it can be written as

$p = mv$

Where,

m = mass

v = Velocity

Our values are given as,

$m = 0.145kg$

$v = 67mi/h = 30m/s$

Replacing we have that,

$p = (0.145)(30)$

$p = 12.45 kg\cdot m/s$

Therefore the magniude of the momentum of the pitched baseball is $12.45 kg\cdot m/s$
