![Definitions and Equations:
Moment of Inertia (): Tendency to resist angular acceleration; the angular equivalent of mass.
In practical terms it is a measure of how hard it is to rotate an object or segment, like a baseball
bat or a body segment. It is the sum of the products of the mass (m) with the square of its
distance from the axis of rotation (k2).
I=mk2
Linear Momentum (L):
L=mv (kg*m/s)
Converting weight to mass
• 1 lb. = 4.45 N
To convert a weight in Newton's into a mass in kg, divide the weight in Newton's by the
acceleration due to gravity (-9.81 m/s²)
If a person has a weight of -900 N (202.25 lbs.), you would calculate their mass by
dividing -900 N by -9.81 m/s2, m -900 N/-9.81 m/s2 = 91.74 kg

7. A baserunner has a mass of 72 kg and is trying to steal 2nd base off in a baseball game.
The baserunner has a velocity of 7.4 m/s. What is his linear momentum?
8. Usain Bolt has a mass of 92 kg and a velocity of 10.43 m/s, based on his 9.58 m/s world
record in his 100 m dash. What is his linear momentum?
9. If Connor McGregor, Tim Tebow and a Cheetah were all in a 200 m running race, who
would have the greatest momentum? Connor McGregor weighs 154 lbs and finished the
race in 30 seconds. Tim Tebow weighs 255 lbs and finished the race in 24 seconds. The](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc885c4d0-eff2-4099-ae7f-848f5ada60ca%2Fcfcf26aa-a62a-424d-a6a3-d752bc603c23%2Fppoq5j_processed.jpeg&w=3840&q=75)
