Answer 1

Answer:

Move forward

Explanation:

The 1st law of motion or we can say that law of inertia is applied here in the 1st law of motion is that an object at rest stays at rest and an object continues in motion until an external force acts on it.

So, on sudden application of brakes on the water tank, the water tank decelerates or may even stop but the water in the tank still has a tendency to move forward due to inertia. Hence the water in the tank would move forward.
