To find the average velocity, we can use the formula:
average velocity = total distance ÷ total time
We are given that the distance is 42.195 km and the time is 2:03:38, which is 2 hours, 3 minutes, and 38 seconds. We need to convert this time into seconds:
2 hours x 60 minutes/hour x 60 seconds/minute = 7,200 seconds
3 minutes x 60 seconds/minute = 180 seconds
Total time = 7,200 + 180 + 38 = 7,418 seconds
Now we can plug in the values:
average velocity = 42.195 km ÷ 7,418 seconds
average velocity ≈ 5.68 m/s
Therefore, the average velocity during the marathon is approximately 5.68 m/s.
To find the average velocity, we can use the formula:
average velocity = displacement ÷ time
We are given that the displacement is 304 m and the time is 180 s. We can plug in the values:
average velocity = 304 m ÷ 180 s
average velocity ≈ 1.69 m/s north
Therefore, the student's average velocity was approximately 1.69 m/s north.
To find the acceleration, we can use the formula:
acceleration = 2 x (distance ÷ time^2)
We are given that the distance is 1 km = 1,000 m and the time is 5.21 s. We can plug in the values:
acceleration = 2 x (1,000 m ÷ (5.21 s)^2)
acceleration ≈ 37.39 m/s^2
Therefore, the acceleration of the car is approximately 37.39 m/s^2.
To find the acceleration, we can use the formula:
acceleration = (final velocity - initial velocity) ÷ time
We are given that the final velocity is 7 m/s, the initial velocity is 0 m/s, and the distance is 35.4 m. We can use the formula:
final velocity^2 = initial velocity^2 + 2 x acceleration x distance

Explanation:
To find the average velocity, we can use the formula:
average velocity = total distance ÷ total time
We are given that the distance is 42.195 km and the time is 2:03:38, which is 2 hours, 3 minutes, and 38 seconds. We need to convert this time into seconds:
2 hours x 60 minutes/hour x 60 seconds/minute = 7,200 seconds
3 minutes x 60 seconds/minute = 180 seconds
Total time = 7,200 + 180 + 38 = 7,418 seconds
Now we can plug in the values:
average velocity = 42.195 km ÷ 7,418 seconds
average velocity ≈ 5.68 m/s
Therefore, the average velocity during the marathon is approximately 5.68 m/s.

To find the acceleration, we can use the formula:
acceleration = (final velocity - initial velocity) ÷ time
We are given that the final velocity is 7 m/s, the initial velocity is 0 m/s, and the distance is 35.4 m. We can use the formula:
final velocity^2 = initial velocity^2 + 2 x acceleration x distance
Solving for acceleration:
acceleration = (final velocity^2 - initial velocity^2) ÷ 2 x distance
Plugging in the values:
acceleration = (7 m/s)^2 ÷ 2 x 35.4 m
acceleration ≈ 6.22 m/s^2
Therefore, the acceleration of the bike is approximately 6.22 m/s^2.
