a professional baseball player can pitch a baseball with a velocity of 44.7m/s towards home plate. If a baseball weighs 1.4 N, h ow much momentum does it have when it hits the catcher units

Answer:
p = 6.25 kg-m/s
Explanation:
It is given that,
Velocity of the baseball, v = 44.7 m/s
Weight of the baseball, W = 1.4 N
Firstly we need to find the mass of the baseball. It can be calculated as :
m = 0.14 kg
The momentum of an object is equal to the product of mass and velocity. It is given by :
p = 6.25 kg-m/s
So, the momentum it have when it hits the catcher is 6.25 kg-m/s. Hence, this is the required solution.
1.4 N is a weight so calculating it's mass 1.4/9.8 = 0.1428 kg momentum will be 0.1428*44.7 = 6.38 kgm/s
