The Position of a Particle Moving Along the Y Axis $y=0.20 \mathrm{~m}+\left(8.0 \frac{\mathrm{~m}}{\mathrm{~s}}\right) t-\left(10 \frac{\mathrm{~m}}{\mathrm{~s}^{2}}\right) \mathrm{t}^{2}$

Multiple Choice

The position of a particle moving along the y axis has a position given by: $y=0.20 \mathrm{~m}+\left(8.0 \frac{\mathrm{~m}}{\mathrm{~s}}\right) t-\left(10 \frac{\mathrm{~m}}{\mathrm{~s}^{2}}\right) \mathrm{t}^{2}$ Is there any time interval during which the particle is not moving?

A) Yes, from 0.60 s to 1.00 s.
B) Yes, from 0.795 s to 0.805 s.
C) Yes, at the time t = 0.80 s.
D) No, the velocity is never zero.
E) No, an instant is not the same as a time interval.
