1. Multiply length times width as if they were integer number:
Now place the decimal point. To do it we have to keep in mind that the result will have as many decimals as the sum of the decimals of each number. In this case, only the width had one decimal, it means that the result will only have one decimal:
Answer:
The resultant velocity is 12.21 m/s.
Step-by-step explanation:
We are given that the water from a fire hose follows a path described by y equals 2.0 plus 0.9 x minus 0.10 x squared (units are in meters).
Also, v Subscript x is constant at 10.0 m/s.
The water from a fire hose follows a path described by the following equation below;
The velocity of the component is constant at =
and the point at which resultant velocity has to be calculated is (9.0,2.0).
Let the velocity of x and y component be represented as;
Now, differentiating the above equation with respect to t, we get;
Now, putting in the above equation;
= 7 m/s
Now, the resultant velocity is given by =
= = 12.21 m/s
