Question

# Starting from rest at S=0, a boat travels in a straight line with an acceleration as shown by the a-s graph. The boat speed at s=40,90 and 200 m is

- 12.7 m/s, 22.8 m/s, 36.1 m/s
- 12.7 m/s, 32.4 m/s, 30.0 m/s
- 12 m/s, 24 m/s, 50 m/s
- 12.7 m/s, 22.8 m/s, 35 m/s

## The correct answer is: 12.7 m/s, 22.8 m/s, 36.1 m/s
