Answer:
The speed of the rain is [tex]v_R = 95.3 km/hr[/tex]
Explanation:
From the question we are told that
The initial speed and direction of the car is [tex]v = 55 \ k/hr\[/tex]
The angle made with the horizontal is [tex]\theta = 60^o[/tex]
The velocity of rain is [tex]v_R[/tex]
An illustrate of this question is shown on the first uploaded image
From the diagram we see that
[tex]tan \theta = \frac{v_R}{v }[/tex]
=> [tex]v_R = v * tan \theta[/tex]
substituting values
[tex]v_R = 55 * tan (60)[/tex]
[tex]v_R = 95.3 km/hr[/tex]
