Answer:
p = 4000 kg-m/s
Explanation:
Given that,
The mass of a truck, m = 200 kg
Speed of the truck, v = 20 m/s
We need to find the momentum of the truck. The formula for momentum is given by :
p = mv
so,

So, the momentum of the truck is equal to 4000 kg-m/s.
The right answer is B. hope this helps you :)
Answer:
Velocity has both speed and direction. Speed is constant. ... Speed is measured over time.
