Question

Calculate average velocity of an object which starts from rest and gains a speed of 30 m/s while moving in a straight path for 2 seconds.

10 m/s

20 m/s

15 m/s

8.5 m/s

​

Answer 1

Answer:

15m/s is the answer.

Explanation:

Initial Velocity = 0m/s (since the body was at rest)

Final Velocity = 30m/s

Time = T

Averge velocity = (Initial + Final)/2

= (0 + 30)/2

= 30/2

= 15m/s
