Answer:
<em>Both vehicles move east at 3.97 m/s</em>
Explanation:
<u>Law Of Conservation Of Linear Momentum </u>
It states that the total momentum of a system of bodies is conserved unless an external force is applied to it. The formula for the momentum of a body with mass m and speed v is:
P=mv.
If we have a system of two bodies, then the total momentum is the sum of both momentums:
If a collision occurs and the velocities change to v', the final momentum is:
Since the total momentum is conserved, then:
P = P'
Assume both masses stick together after the collision at a common speed v', then:
The common velocity after this situation is:
Assuming east direction to be positive, we have an m1=1459 kg car traveling west at v1=-43 m/s. An m2=9755 kg truck is traveling east at v2=11 m/s. They collide head-on and stick together after that.
Computing the resultant velocity after the collision:
v' = 3.97 m/s
Both vehicles move east at 3.97 m/s
