Answer:

Given -

  • Initial velocity of the ball, u = 0 m/s
  • final velocity of the ball, v = 12 m/s
  • Time taken = 36 sec

[tex] \\ [/tex]

To find -

  • Acceleration of the ball.

[tex] \\ [/tex]

Solution -

[tex] \\ \sf \: A = \frac{v - u}{t} \\ \\ \\ \implies \sf \: A = \frac{12 - 0}{36} \\ \\ \\ \implies \sf \: A = \frac{12}{36} \\ \\ \\ \implies \sf \underline{A = 0.33 \: m \: / {s}^{2} } \\ [/tex]

Therefore, the acceleration of the ball is 0.33 m/s².
