Answer:
Therefore the average speed of a rock launched 700km from a catapult in 15 seconds is 46666.66 m/s or 46.66 km/s.
Explanation:
Given:
Total Distance Covered = 700 km = 700 × 1000 meter = 700000 m
Time taken = 15 seconds = 15 s
To Find:
Average speed of a rock = ?
Solution:
Average speed:
Average speed is defined as the rate of total distance covered in per unit time.
It is given as
[tex]\textrm{Average speed }=\frac{\textrm{Total Distance}}{Time}[/tex]
Substituting the given values we get
[tex]\textrm{Average speed }=\frac{700000}{15}=46666.66\ m/s[/tex]
Therefore the average speed of a rock launched 700km from a catapult in 15 seconds is 46666.66 m/s or 46.66 km/s.
