The expected damages associated with two types of perfectly plastic collisions are to be compared. In the first case, the car traveling to the left is much larger than the car traveling to the right, but each have the same velocities. In the second case, the car impacts a massive concrete wall. In which case would you expect the car to be more damaged

Transfer of electrons. hope it !

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction 

If your workout exceeds an hour you should substitute "a sports drink" for water.hope my answer has you : )
