Cart A and cart B are moving toward each other. They collide and come to rest at the point of impact. From this observation, we can conclude that the carts
have equal masses
were moving with equal and opposite momentum
were moving with equal and opposite velocities
were moving with equal kinetic energies

Respuesta :

Answer:

were moving with equal and opposite momentum

Explanation:

As we know that in all collision net external force on the system of two masses will be ZERO

so we can use momentum conservation

[tex]F = \frac{\Delta P}{\Delta t}[/tex]

if we have

F = 0

[tex]\Delta P = 0[/tex]

[tex]m_1v_1 + m_2v_2 = 0[/tex]

so we have

[tex]m_1v_1 = - m_2v_2[/tex]

so correct answer will be

were moving with equal and opposite momentum
