You are pushing your nephew on a playground swing. The swing seat is suspended from a horizontal bar by two light chains. Assume that the estimation of the length of each chain is 2.0 m. Treat the motion of the child as that of a simple pendulum and assume that for safety the amplitude of the motion is kept small. You give your nephew a light push each time he reaches his closest distance from you. Required:
How much time elapses between your pushes?

No because a circle or pie graph usually shows percentages you'd need a line graph

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 

The correct answer should be b let me know if i’m wrong
