b
Explanation:
From the question we are told that
The pressure of the water in the pipe is
The speed of the water is
The original area of the pipe is
The new area of the pipe is
Generally the continuity equation is mathematically represented as
Here is the new velocity
So
=>
=>
=>
=>
Generally given that the height of the original pipe and the narrower pipe are the same , then we will b making use of the Bernoulli's equation for constant height to calculate the pressure
This is mathematically represented as
Here is the density of water with value
=>
=>
The velocity of B after elastic collision is 3.45m/s
This type of collision is an elastic collision and we can use a formula to solve this problem.
<h3>Elastic Collision</h3>The data given are;
- m1 = 281kg
- u1 = 2.82m/s
- m2 = 209kg
- u2 = -1.72m/s
- v1 = ?
Let's substitute the values into the equation.
From the calculation above, the final velocity of the car B after elastic collision is 3.45m/s.
