Question

A man is in a topless car with a speed of 18 kmph. On a raing day. To protect himself from rain
he holds the umbrella at 60° to vertical. The velocity of rain is​

Answer 1

Answer:

The velocity of rain is​ 10.4 km/h

Explanation:

As we know that the rain is falling with respect to the motion of car

so here we will have

$tan\theta = \frac{v_c}{v_R}$

now we will have

$\theta = 60 ^o$

$v_c = 18 km/h$

now we have

$v_R = \frac{v_c}{tan60}$

$v_R = 10.4 km/h$
