Explanation:
It is given that, the water from a fire hose follows a path described by equation :
........(1)
The x component of constant velocity,
We need to find the resultant velocity at the point (2,3).
Let and
Differentiating equation (1) wrt t as,
When x = 2 and
So,
Resultant velocity,
v = 6.4 m/s
So, the resultant velocity at point (2,3) is 6.4 m/s. Hence, this is the required solution.
