Answer:
6.478m/s
Explanation:
There are some assumptions to be made. To answer this problem, I assume that Maggie is walking in a straight line and that she initially starts off with a velocity of 1.4m/s.
Maggie initially walks at a speed of 1.4m/s. We are also told that the acceleration is 0.2m/s^2 and that she walked a total of 100m. Therefore our parameters are:
[tex]v_i=1.4\frac{m}{s}\\a=0.2\frac{m}{s^2}\\d=100m\\v_f=?[/tex]
Looking up kinematic equations that contains these parameters are
[tex]v_f^2=v_i^2+2ad\\v_f^2=(1.4\frac{m}{s})^2+2*(0.2\frac{m}{s^2})(100m)\\v_f^2=41.96\frac{m^2}{s^2}\\v_f=6.478\frac{m}{s}[/tex]
