Answer:
Yes, the car driver is exceeding the given limit.
Explanation:
<u>Given:</u>
- Speed of the car, v = 38.0 m/s.
- Speed limit of the highway,
We know,
1 mi = 1.60934 km.
1 km = 1000 m.
Therefore, 1 mi = 1.60934 × 1000 m = 1609.34 m.
1 hour = 60 minutes.
1 minute = 60 seconds.
Therefore, 1 hour = 60 × 60 seconds = 3600 seconds.
Using these values,
Therefore,
Clearly,
which means, the car driver is exceeding the given speed limit.
Answer:
The magnitude of the angular acceleration is
Explanation:
From the question we are told that
The angular speed of CD is
time taken to decelerate is
The final angular speed is
The angular acceleration is mathematically represented as
substituting values
The negative sign show that the CD is decelerating but the magnitude is
