Ignoring fluid resistance, football will <span>maintain a constant speed until other forces accelerate the football.</span>
The speed of the water in the wider part will be 1.194 m/sec. Speed is a time-based quantity. Its SI unit is m/sec.
<h3> What is speed?</h3>
Speed is defined as the rate of change of the distance or the height attained.
The given data in the problem is;
The initial diameter is,
initial radius,

The initial crossection area;

The final crossection area;

The initial flow rate is;
R = density ×velocity ×area

The speed of the water in the wider part will be;
From the continuity equation;

Hence, the speed of the water in the wider part will be 1.194 m/sec.
