## Trigonometry (10th Edition)

1800$^{\circ}$
1. We need to know number of rotations per second: $\frac{600rot}{1min}$$\times$$\frac{1min}{60sec}$ = 10 rot/sec 2. Then how much rotations in 0.5 seconds $\frac{1}{2}$sec$\times$$\frac{10rot}{1sec} = 5 rotations 3. As we know each rotation is 360^{\circ}, therefore we just need to multiply: 5rot\times$$\frac{360^{\circ}}{1rot}$ = 1800$^{\circ}$
