Rain is falling at an angle of \(30^{\circ}\) from the vertical due to the wind with a speed of \(40 \mathrm{~m} / \mathrm{s}\). A car is travelling horizontally in the direction opposite to the wind, at a speed of \(40 \mathrm{~m} / \mathrm{s}\). At what angle from the vertical will it experience the rain falling from? 
- A \(30^{\circ}\)
- B \(60^{\circ}\)
- C \(90^{\circ}\)
- D \(120^{\circ}\)
Answer & Solution
Correct Answer
(B) \(60^{\circ}\)
Step-by-step Solution
Detailed explanation
The given situation can be shown in figure below, As the rain makes an angle of \(30^{\circ}\) with the vertical. So, the angle made by it with the horizontal is \[ \theta=90^{\circ}-30^{\circ}=60^{\circ} \] And as the car is moving in horizontal direction with the same speed as…
