Problem

The position of a toy car moving along a straight line is recorded every

2\,\text{s}

as follows:

t=0\,\text{s}:\;0\,\text{m}

t=2\,\text{s}:\;2\,\text{m}

t=4\,\text{s}:\;6\,\text{m}

t=6\,\text{s}:\;12\,\text{m}

Which statement best describes the motion of the car over the

6\,\text{s}

interval? (a) Uniform motion at

2\,\text{m/s}

. (b) Non-uniform motion with decreasing speed. (c) Non-uniform motion with increasing speed. (d) Non-uniform motion with constant acceleration of

1\,\text{m/s}^2
