Question

What’s the correct answer

Answer 1

According to 1st equation of motion :

`\boxed{ \boxed{v = u + at}}`

where,

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

let's solve for t

`\hookrightarrow \: 17.63 = 0 + 2.13t`

`\hookrightarrow \: t = (17.63)/(2.13)`

`\hookrightarrow \: t = 8.276 \approx 8.28\: \: sec`
