A baseball has a mass of about 155 g. What is the magnitude of the momentum of a baseball thrown at a speed of 86 miles per hour

Magnitude of the momentum (P) = 5.96 Kg.m /s (Approx)

Explanation:

Given:

Mass of baseball (m) = 155 gram = 0.155 kg

Velocity (v) = 86 miles/ hour

Find:

Magnitude of the momentum (P)

Computation:

1 mile = 1,609.344 meters

So,

Velocity (v) = 86 × (1,609.344 / 3600)

Velocity (v) = 38.45 m/s

Magnitude of the momentum (P) = mv

Magnitude of the momentum (P) = (0.155)(38.45)

Magnitude of the momentum (P) = 5.96 Kg.m /s (Approx)
