In a parking garage, both cars were parked in their own respective spaces, one behind the other. The blue car's driver accidently pressed the accelerator pad instead of the brake pad, thus backing into the green car. The force applied by the blue car was 15N and the mass of the blue car is 1500kg. What was the rate of acceleration of the blue car backing into the green car?

Milliseconds. . . . . .

Then the answer would be d then

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
