Answer:
Explanation:
Initial velocity → 10Km/h → 10 X 5/18 ⇒ 2.77777777778 m/s
Final Velocity → 15Km/h → 15 X 5/18 ⇒ 4.16666666667 m/s
Time → 2sec
Acceleration =Change in velocity/Time
a = v-u/t
a = 4.16666666667-2.77777777778
a = 1.38888888889m/s²
HOPE IT HELPS!!!

We know that,
Acceleration is defined as ratio of change in velocity to the time interval.
Converstion :-
1kmph = 5/18mps
15kmph = 4.17mps
10kmph = 2.78mps
Then,
- Acceleration is a vector quantity.
- Accelerataion has both magnitude as well as direction.
- Acceleration can be positive, negative and zero.
