Answer:

<h2>the car must move with the speed</h2><h2> $v = 72.16 m/s$ </h2>

Explanation:

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

so as per the formula of momentum we have

$P = mv$

so we have

$m_1v_1 = m_2v_2$

so we will have

$910 \times 18 = 227 v$

$v = 72.16 m/s$

So the car must move with the speed

$v = 72.16 m/s$
