We know that,

  • [tex]a = \dfrac{v - u}{t} [/tex]

where,

  • a = avg acceleration

  • v = final velocity = 24 m/s

  • u = initial velocity = 0 m/s

  • t = time taken = 8 sec

so, let's find avg acceleration :

  • [tex]a = \dfrac{24 - 0}{8} [/tex]

  • [tex]a = \dfrac{24}{8} [/tex]

  • [tex]a = 3 \: \: m {s}^{ - 2} [/tex]

hence, correct choice is C
