The bus traveled 500 km east and 300 km south. What is the distance and the displacement?
- A.
800 km and 583 km SE
- B.
450 km and 835 km SE
- C.
630 km and 538 km SE
Correct Answer
A. 800 km and 583 km SEExplanation
The distance traveled by the bus is the sum of the distances traveled in each direction, which is 500 km + 300 km = 800 km. The displacement is the straight-line distance from the starting point to the ending point, which can be calculated using the Pythagorean theorem. The displacement is the square root of (500 km)^2 + (300 km)^2 = 583 km. The direction of the displacement can be determined as southeast (SE) based on the relative positions of the starting and ending points.Rate this question:

Jermaine runs 3 laps around a 400 meter track. Why is displacement equal to 0?
- A.
Because the end point is the same as the starting point.
- B.
Because he runs very fast.
- C.
Because the shape of the track is circular.
Correct Answer
A. Because the end point is the same as the starting point.Explanation
The displacement is equal to 0 because the end point of Jermaine's run is the same as the starting point. Displacement measures the change in position from the initial point to the final point, and since Jermaine ends up back where he started, there is no change in position. This is regardless of how fast he runs or the shape of the track.Rate this question:

- A.
110 km/h northeast
- B.
110 km/h eastnorth
- C.
110 km/h southeast
Correct Answer
A. 110 km/h northeastExplanation
The car traveled a total distance of 550 km in 5 hours, with 200 km north and 350 km east. To find the velocity, we need to divide the total distance by the total time. Therefore, the velocity of the car is 550 km / 5 hours = 110 km/h. Since the car traveled more distance towards the east than towards the north, the velocity is in the northeast direction.Rate this question:

Miguel flies the plane directly west for 20 miles, then turns to the south and flies another 30 miles in 0.5 hour. What is the velocity of the plane?
- A.
72 miles/h SW
- B.
72 km/h SW
Correct Answer
A. 72 miles/h SWExplanation
Miguel first flies west for 20 miles, which gives him a westward velocity. Then, he turns south and flies another 30 miles in 0.5 hours. To find the velocity, we need to divide the total distance traveled (50 miles) by the total time taken (0.5 hours). This gives us a velocity of 100 miles/hour. Since Miguel flew west for 20 miles and south for 30 miles, we can use the Pythagorean theorem to find the resultant velocity. The resultant velocity is the hypotenuse of a right triangle with sides of 20 miles (west) and 30 miles (south). Using the theorem, we find that the resultant velocity is 36.06 miles/hour. Since the resultant velocity is in the southwest direction, the correct answer is 72 miles/hour southwest.Rate this question:
