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]
