Answer:

a = 6.25 m/s²

Explanation:

given,

initial speed, u = 0 m/s

final speed, v = 62.5 m/s

time, t = 10 s

acceleration = ?

we know,

using equation of motion

v = u + at

[tex]a = \dfrac{v-u}{t}[/tex]

[tex]a = \dfrac{62.5-0}{10}[/tex]

      a = 6.25 m/s²

Hence, acceleration comes out to be equal to 6.25 m/s²
