Question

a) An object moves 18 m in the first
3 s, 22 m in the next 3 s and 14 m in
the last 3 s. What is its average
speed?​

Answer 1

Answer:

since time intervals are the same you can directly add the 3 distances. and then find speed.

18+22+14=54 m

total time=3x3=9

speed =6 m /s

Answer 2

Answer:

speed = 6 m/s

Explanation:

speed = 18 + 22 + 14 = 54 m

           = 54 / 6 = 9

           = 9 = 9            ... (same)

         

ans = speed  =  6 m/s
