Answer:

A) 0

Explanation:

Given;

the ball's initial velocity, Vi = 15 m/s

the ball's final velocity, Vf = 15 m/s

time of motion of the ball, t = 0.01 s

Acceleration is the change in velocity with time. Measured in meter per second square (m/s²).

The acceleration of the ball is calculated as follows;

[tex]a = \frac{dv}{dt} = \frac{V_f - V_i}{t} = \frac{15 \ m/s \ \ - \ \ 15 \ m/s}{0.01 \ s} \ = \ \frac{0}{0.01 \ s} \ = \ 0[/tex]

Therefore, the acceleration of the ball is 0.
