Problem

A cart moves along a straight line with initial position

x_{0}=+4.0\,\text{m}

and initial velocity

v_{0}=−2.0\,\text{m/s}

(negative indicates motion to the left). The cart undergoes a constant acceleration of

+1.0\,\text{m/s}^{2}

. What is the cart’s position after 5.0\,s? a)

-6.5\,\text{m}

+16.5\,\text{m}

+6.5\,\text{m}

+2.5\,\text{m}
