A car and a truck are moving next to each other on the highway. The truck has a mass of 910 kg and the car’s mass is 227 kg. IF their momentums are equal and the truck is moving at 18 m/s, what is the speed of the car?

Respuesta :

Answer:

the car must move with the speed

[tex]v = 72.16 m/s[/tex]

Explanation:

As we know that the momentum of the car and truck is same

so as per the formula of momentum we have

[tex]P = mv[/tex]

so we have

[tex]m_1v_1 = m_2v_2[/tex]

so we will have

[tex]910 \times 18 = 227 v[/tex]

[tex] v = 72.16 m/s[/tex]

So the car must move with the speed

[tex]v = 72.16 m/s[/tex]
