In this question, we are going to calculate the velocity of rain with respect to car and then with respect to earth.
00:12
But before that, for this, we must draw a free body diagram which represent the direction of both the car and the rain.
00:24
So that is true.
00:27
Now, this diagram represents the direction of both the car and the rain.
00:34
Now here, vr represent the velocity of the rain drop.
00:40
Vc is the velocity of the car in east direction.
00:45
Vrc is the velocity of the rain with respect to the car.
00:50
Now, using the above figure, the velocity of the rain with respect to the car is given by vc equal to vrc sine theta.
01:05
Now here, theta is the angle of the rain drop with the vertical.
01:09
Now we rearrange this equation for vrc...
