Answer 2

The time is 2.91 s.

Step-by-step explanation:

Given that,

Initial velocity = 3.44 m/s

Final velocity = 20.9 m/s

Acceleration = 6.00 m/s²

We need to calculate the time

Using equation of motion

`v = u+at`

`t=(v-u)/(a)`

Where, u = initial velocity

v = final velocity

a = acceleration

Put the value in the equation

`t =(20.9-3.44)/(6.00)`

`t=2.91\ s`

Hence, The time is 2.91 s.
