Answer:
[tex]\boxed{\text{7 m/s}}[/tex]
Explanation:
The formula for average speed is
[tex]\text{speed} = \dfrac{\text{distance}}{\text{time}}\\\\s = \dfrac{d}{t}[/tex]
Data:
d = 35 m
t = 5 s
Calculation:
[tex]s = \dfrac{\text{35 m}}{\text{5 s}} = \text{7 m/s}[/tex]
The average speed of the ball is [tex]\boxed{\textbf{7 m/s}}[/tex]
