Question

Saki is ice-skating to the left with a velocity of 5\,\dfrac{\text{m}}{\text{s}}5sm​5, start fraction, start text, m, end text, divided by, start text, s, end text, end fraction. A steady breeze starts blowing, causing Saki to accelerate leftward at a constant rate of 1.5\,\dfrac{\text{m}}{\text{s}^2}1.5s2m​1, point, 5, start fraction, start text, m, end text, divided by, start text, s, end text, squared, end fraction.

After 6\,\text s6s6, start text, s, end text, what is Saki's velocity?
Answer using a coordinate system where rightward is positive.​
