Answer:
The speed of the small engine car is _equal to_ the speed of the massive cargo car. The magnitude of the acceleration of the small engine car is _equal to_ the magnitude of the acceleration of the massive cargo car because _the cars speeds cannot change by different amounts_ .
Explanation:
The two cars are connected, hence, they move with the same speed at all points in time.
Blank 1: Option C is the correct answer.
Blank 2: Option C is the correct answer.
Blank 3: Option B is the correct answer.
Velocity and Acceleration
The rate of change of position or displacement of an object within a given time interval is called the velocity of the object. The rate of change in the velocity of an object within the given time interval is called the acceleration of the object. The velocity and acceleration of an object depend upon time.
Given that A train composed of a small engine car and a massive cargo car is connected as they move along a track.
It means that the car and cargo will move with the same speed as they are connected to a train.
Thus, the speed of the car and cargo will be equal. Option C represents the correct answer for Blank 1.
The velocity of the engine car and massive cargo is equal. Hence the acceleration will also equal. Option C is the correct answer for Blank 2.
The engine car and massive cargo are connected with the truck all the time. Hence their speed will not change at any point. Option B will be the correct answer for Blank 3.
