Question

QIII.2 What is the average speed and
velocity of the ball in the entire motion?​

Answer 1

Answer:

30 is average velocity and speed.

Explanation:

In the first 3 seconds the ball travels 'x' displacement.

s=v*t

x=30*3=90

In the second 3 seconds the ball travels 'x' displacement.

s=v*t

x=30*3=90.

Average speed = 90+90/3+3= 180/6=30.

Therefore average speed and velocity=30.
