Question
A turtle crawls along a straight line, which we’ll
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 1t2 = 50.0 cm +
(2.00 cm/s)t - (0.0625 cm/s2)t2. 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?
