SUMMARY

The momentum of a baseball weighing 0.145 kg and thrown at a velocity of 40 m/s is calculated using the formula p = mv. The correct calculation yields a momentum of 5.8 kg m/s. The user initially submitted an incorrect answer of 116 J, which is a unit of energy, not momentum. The correct unit for momentum is kg m/s.

PREREQUISITES
  • Understanding of basic physics concepts, specifically momentum.
  • Familiarity with the formula p = mv (momentum equals mass times velocity).
  • Knowledge of units of measurement in physics, particularly kg m/s.
  • Basic arithmetic skills for performing multiplication.
NEXT STEPS
  • Review the principles of momentum in physics.
  • Study the differences between momentum and energy, including their respective units.
  • Practice additional momentum calculations with varying masses and velocities.
  • Explore real-world applications of momentum in sports and physics.
USEFUL FOR

Students studying physics, educators teaching momentum concepts, and anyone interested in understanding the mechanics of sports like baseball.

Question is:
A .145kg baseball is thrown at 40 m/s (~89.5mph). What is the momentum of the baseball?
Enter units of momentum as kg m/s


I have used the following solutions for the question, but the answer I'm submitting is coming back wrong.

I have entered:
116 J
5.8 kgm/s

The formula I used to solve the question is p=mv p=(.145kg)(40m/s) = 5.8
Please help...
