Answer 2

The angle in degrees turned by the engine in 10 second is 6.36°

Step-by-step explanation:

Speed = 60 km /hr

1 km = 1000 m

1 hr = 3600 seconds

Speed in m/s =$\frac{60 \times 1000}{3600}=16.67 m/s$

Time= 10 seconds

$Distance= Speed \times Time$

$Distance=16.67 \times 10$

$Distance=166.7 m$

Length of arc = 166.7 m

radius of track is 1500 m

Formula of length of arc = $\frac{\theta}{360} \times 2\pi r$

$166.7 =\frac{\theta}{360} \times 2 \times \frac{22}{7} \times 1500$

$\theta =6.36$

Hence the angle in degrees turned by the engine in 10 second is 6.36°
