Kinematic equations: numerical calculations

A bumblebee is flying to the right when a breeze causes the bee to slow down with a constant leftward acceleration of magnitude $0.50\,\dfrac{\text m}{\text s^2}$0, point, 50, start fraction, start text, m, end text, divided by, start text, s, end text, squared, end fraction. After $2.0\,\text{s}$2, point, 0, start text, s, end text, the bee is moving to the right with a speed of $2.75\,\dfrac{\text m}{\text s}$2, point, 75, start fraction, start text, m, end text, divided by, start text, s, end text, end fraction.

Give the correct sign for your answer, using a coordinate system where rightward is positive.
