Problem

A turntable starts from rest at

t=0

. Its angular velocity increases uniformly from

0

6\,\text{rad/s}

during the first

3\,\text{s}

and then remains constant at

6\,\text{rad/s}

for the next

2\,\text{s}

. What is the total angular displacement of the turntable from

t=0

t=5\,\text{s}

? a)

24\,\text{rad}

18\,\text{rad}

21\,\text{rad}

15\,\text{rad}
