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.
If the temperature is increased the particles gain more kinetic energy or vibrate faster. This means that they move faster and take more space.
Answer:
mass.
