Answer 1

The value of the speed of the car, for the front glass of the car to get wet, $V_c \geq 10 \ m/s$.

The given parameters:

• Speed of the car, = Vc
• Speed of the rain, = 10 m/s

The relative velocity of the car with respect to the falling rain is calculated as;

$V_{C/R} = V_C- V_R$

• If the speed of the car equals the speed of the rain, the rain will fall behind the car.
• If the speed of the rain is greater than speed of the car, the rain will fall far in front of the car.
• If the speed of the car is greater than speed of the rain, the rain will fall on the car.

Thus, for the front glass of the car to get wet, $V_c \geq 10 \ m/s$.
