Question

Georgia is jogging with a velocity of 4 m/s when she accelerates at 2 m/s2 for 3 seconds. How fast is Georgia running now?

Answer 1

Given :

Initial speed=u=4m/s

Final speed=V=?

a=2m/s²

t=3sec

From first equation of motion :

V=u+at

V=4+2x3=4+6=10m/s

∴Georgia is running at the speed of 10m/s.

Answer 2

Here,

Initial speed(u)=4m/s

acceleration(a)=2m/s²

time(t)=3sec

From Ist equation of motion :

V=u+at

V=4+2x3

V=4+6

V=10m/s

Hence, Georgia is running at the speed of 10m/s.
