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?+
