Problem

A potter’s wheel starts from rest and follows three successive stages: 1. It accelerates at

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

for

4.0\,\text{s}

. 2. It then spins at the constant angular speed reached at the end of stage 1 for

6.0\,\text{s}

. 3. Finally, it decelerates uniformly to rest in

5.0\,\text{s}

. What is the total angular displacement of the wheel during the entire process? (a)

57\,\text{rad}

(b)

63\,\text{rad}

(c)

48\,\text{rad}

(d)

75\,\text{rad}
