an object moves 42km [w] per day if the object moves for 7.0 h a day what was his average velocity in m/s
First, we need to convert the distance traveled into meters:
42 km = 42,000 m
Next, we need to convert the time traveled into seconds:
7.0 hours = 7.0 * 60 * 60 = 25,200 seconds
Now, we can calculate the average velocity:
Average velocity = Distance / Time
Average velocity = 42,000 m / 25,200 s
Average velocity ≈ 1.67 m/s
Therefore, the average velocity of the object was approximately 1.67 m/s.
