If you are given the mass of an object in pounds, the time in seconds, and the distance in feet, what must you do before you can calculate the momentum in SI units?

Answer: First you must convert pound in kilogram, and feet in meter

Explanation:

To calculate momentum we use.

p=m*V

mass-m

speed-V

distance and time are used to calculate velocity (speed)

You are given:

mass - in pounds

for distance - in feet

before you do any calculation first you have to convert pounds in kilograms

and feet in meters.
