a turtle crawls along a straight line, which we will call the x-axis with the positive direction to the right. the equation for the turtle’s position as a function of time is x(t) = 50.0 cm + (2.00 cm/s)t - (0.0625 cm/s^2)t^2. (a) find the turtle’s initial velocity, initial position, and initial acceleration. (b) at what time t is the velocity of the turtle zero? (c) how long after starting does it take the turtle to return to its starting point? (d) at what times t is the turtle a distance of 10.0 cm from its starting point? what is the velocity (magnitude and direction) of the turtle at each of those times?+

The answer is orbit around nucleus

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
