Question

calculate the linear momentum of a pickup truck that has a mass of 1000kg, and is traveling eastward at 20 m/s

Answer 1

Momentum = Mass × Velocity

From the given data, Mass is 1000kg and Velocity is 20m/s

Momentum = 1000 × 20

`Momentum = 20000 {kgms}^( - 1)`

Answer 2

The momentum of the truck is
`2* 10^4\ kg-m/s`.

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`

`p=2* 10^4\ kg-m/s`

So, the linear momentum of the truck is
`2* 10^4\ kg-m/s`. Hence, this is the required solution.
