Question

a ball is thrown horizontaly formed point A travells along a straight line and strikes the wall to a point B which is at a distance of 10m and rebounds to the same point A in 8sec Find the average of speed and average velocityof ball​

Answer 1

Answer:

average speed=total distance/total time

ans= 2.5 m/s

Answer 2

Answer: 2.5 m/s

Explanation:

Distance from A to B = 10m

Distance from B to A = 10m

Total distance = 20m

Time = 8 sec

Average speed = Distance/Time

Speed = 20/8

Speed = 2.5 m/s
