A truck is speeding up as it travels on an interstate. The truck's momentum (in kg - m/s) is proportional to the truck's speed (in m/s). a. At some moment

the truck's momentum is 50600 kg - m/s and the truck's speed is 23 m/s. At this moment, the truck's momentum (in kg -m/s) is how many times as large as the truck's speed (in m/s)? b. This means that as the truck travels, the truck's momentum (in kg - m/s) is always times as large as the truck's speed (in m/s). c. If the truck is traveling at 17 m/s, what is the truck's momentum?
