A professional baseball player can pitch a baseball with a velocity of 44.7 m/s towards home plate. If a baseball weighs 1.4 N, how much momentum does it have when it hits the catcher’s mitt?

Explanation:

weight = 1.4 N

we need to calculate mass first,

mass = weight / g

mass = 1.4 / 9.8

= 0.142 kg

momentum = mass × velocity

momentum = 0.142 × 44.7

momentum = 6.3474 kg m/s
