Answer:
Her acceleration is 0 m/s²
Explanation:
We note that the motion of the girl is on a straight road, therefore;
The vertical acceleration (e.g. due to gravity, <em>g)</em> on the horizontal motion = 0
The horizontal acceleration, a = (Change in velocity, Δv)/(Change in time, Δt)
For uniform velocity, the change in velocity, Δv = 0
Therefore, fore any change in time, Δt, we have;
a = Δv/Δt
Her acceleration, a = 0/Δt = 0
Her acceleration, a = 0 m/s²
