Answer:
The momentum of the truck is
.
Step-by-step explanation:
It is given that,
Mass of the truck, m = 1000 kg
Speed of the truck, v = 20 m/s (towards east)
Let p is the linear momentum of a truck. It is equal to the product of mass and velocity. Mathematically, it is given by :
p = m v
![p=1000\ kg* 20\ m/s](https://img.qammunity.org/2020/formulas/physics/middle-school/y7ckvd06wwr4207duvj5lb6t0wl5580a2f.png)
![p=2* 10^4\ kg-m/s](https://img.qammunity.org/2020/formulas/physics/middle-school/lrg9x48elbilfgd357m7tznn63iiin1p67.png)
So, the linear momentum of the truck is
. Hence, this is the required solution.
