Aspeeder traveling at a constant speed of 111 km/h races past a billboard. a patrol car pursues from rest with constant acceleration of (7 km/h)/s until it reaches its maximum speed of 165 km/h, which it maintains until it catches up with the speeder. how long does it take the patrol car to catch the speeder if it starts moving just as the speeder passes

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
