Answer:
2.5m/s^2
Step-by-step explanation:
The average acceleration (
�
avg
a
avg
) can be calculated using the following formula:
�
avg
=
Δ
�
Δ
�
a
avg
=
Δt
Δv
where:
Δ
�
Δv is the change in velocity
Δ
�
Δt is the change in time
In this case:
The initial velocity (
�
initial
v
initial
) is 0 m/s.
The final velocity (
�
final
v
final
) is 25 m/s.
The time period (
Δ
�
Δt) is 10 seconds.
So, the change in velocity (
Δ
�
Δv) is:
