According to 1st equation of motion :

[tex]\boxed{ \boxed{v = u + at}}[/tex]

where,

  • v = final velocity
  • u = initial velocity
  • a = acceleration
  • t = time

let's solve for t

[tex] \hookrightarrow \: 17.63 = 0 + 2.13t[/tex]

[tex] \hookrightarrow \: t = \dfrac{17.63}{2.13} [/tex]

[tex] \hookrightarrow \: t = 8.276 \approx 8.28\: \: sec[/tex]
