Answer:
The car has the greatest momentum, 160000 [kg*m/s]
Explanation:
In order to solve this problem we must remember that linear momentum is defined as the product of mass by Velocity. In this way we have the following equation
P = m*v
where:
P = lineal momemtum [kg*m/s]
m = mass [kg]
v = velocity [m/s]
Therefore we must calculate the momentum for both the truck and the car.
For the car
Pc = 2000*80
Pc = 160000 [kg*m/s]
For the Truck
Pt = 7000*20
Pt = 140000 [m/s]
The car has the greatest momentum
