Question

What is Maggie´s final velocity when she rollerskates if she accelerates at a rate of 2.0 m/s2 heading south for 5.5 seconds starting from rest?

Answer 1

Answer:

We have given that,

u (initial velocity) =0m/s

a =2m/s^2

and, time =5.5sec

to find : v

solution :

so, by first equation of motion,

v =u +at

v = 0 + 2 * 5.5

v = 11.0m/s

Hence, Maggie's final velocity will be 11m/s
