Problem

A toy car moves around a circular track of radius

2.0\,\text{m}

. Starting from rest, its angular acceleration about the centre is constant at

1.5\,\text{rad\,s}^{-2}

. Find the magnitude of its total linear acceleration

4\,\text{s}

after it starts. a)

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

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

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

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