Answer:
The average velocity of the ball is 1.355 cm/s.
Explanation:
Given;
initial displacement of the ball, x₁ = 8.4 cm
final displacement of the ball, x₂ = 4.2 cm
initial time, t₁ = 3.0 s
final time, t₂ = 6.1 s
The average velocity of the ball is calculated as;
[tex]v = \frac{\Delta x}{\Delta t} \\\\v = \frac{8.4\ cm\ - \ 4.2 \ cm}{6.1 s - \ 3.0 s} \\\\v = 1.355 \ cm/s[/tex]
Therefore, the average velocity of the ball is 1.355 cm/s.
