Answer:
Velocity is a function of time and defined by both a magnitude and a direction. [1] Often in physics problems, you will need to calculate the initial velocity (speed and direction) at which an object in question began to travel. There are multiple equations that can be used to determine initial velocity. Using the information given in a problem, you can determine the proper equation to use and easily answer your question.

Answer:
B. the force of on the truck due to the collision is exactly equal to the force on the car.
Explanation:
At the time of collision between two objects of unequal or equal masses two forces emerge at the point of collision .They are called action and reaction force . According to third law of Newton , they are equal . So in the instant case of collision between car and truck , force on both of them will be equal.
Forces equal the flag doesn't move either direction
Unequal forces the flag moves in the direction of the greater magnitude force
