Final answer:
Allison Felix's momentum is 584.01 kg m/s.
Step-by-step explanation:
The momentum of an object is defined as the product of its mass and velocity. In this case, Allison Felix's momentum can be calculated using the formula:
Momentum = mass x velocity
Given that Allison Felix's weight is 125 lb and her velocity is 23 mph, we need to convert her weight to mass and her velocity to meters per second to make the units consistent. We can use the conversion factors: 1 lb = 0.4536 kg and 1 mph = 0.447 m/s.
Converting Allison Felix's weight: 125 lb x 0.4536 kg/lb = 56.7 kg
Converting Allison Felix's velocity: 23 mph x 0.447 m/s = 10.3 m/s
Now we can calculate her momentum:
Momentum = 56.7 kg x 10.3 m/s = 584.01 kg m/s
