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?
1 answer:
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
