Given:
Total distance = 1000 kilometer
Total time = 5 hours
To find:
Average speed = ?
Formula used:
= 
Where
= average speed
s = total distance
t = total time
Solution:
Average speed of the jet is given by,
= 
Where
= average speed
s = total distance
t = total time
= 
= 200 km/ h
Thus, average speed of the jet is 200 km/h.
Hence, Option (A) is correct.
Velocity change v time because ACCELERATION=CHANGE IN VELOCITY/TIME
Answer: V = 504m/a
F = 4N
Explanation: please find the attached file for the solution
Work = (force) x (distance) =
(200 N) x (3.5 m) = <em>700 joules</em>
