Problem

The velocity of a scooter increases uniformly from

0\,\text{m/s}

20\,\text{m/s}

10\,\text{s}

. During these

10\,\text{s}

, how would you classify its motion and why? a) Uniform, because acceleration is constant at

2\,\text{m\,s}^{-2}

. b) Non-uniform, because its velocity is changing with time. c) Uniform, because acceleration is zero. d) Non-uniform, because its direction is changing.
