Answer 2

4 m/s2 in negative acceleration

Step-by-step explanation:

From the question.

Acceleration= change in velocity ÷ time.

V1-V0÷time.

That is final velocity minus initial velocity divided by time.

25-65÷10.

-40/10=4m/s.

The acceleration is -4m/s.

The answer is 4m/s negative acceleration.
