A child is playing hook-a-duck. The mass of each duck is 50 g. The line has a spring constant of 500 N/m. Calculate the weight of the rubber duck. (Take g = 10 N/kg)
Calculate the extension of the line when a duck is hooked.

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

Idon't understand is there supposed to be a list or something if there is pm or add in under this message i will do my best to .
