Justine is ice-skating at the Lloyd center what is her final velocity if she accelerates at a rate of 2.0m/s for 3.5 seconds?

7 m/s

Explanation:

Acceleration,

Where v and u are the final and initial velocities of the Justine respectively, t is the time taken for Justin to attain final velocity.

Making v the subject then

v=at+u

Taking u as zero then

Substituting 3.5 for t, 2 as a then

v=3.5*2=7 m/s

answer; /// the correct )
