Rain is falling with a sped of `12sqrt(2)m//s` at an angle `45^@` with the vertical line. A man in a glider going at a speed of `u` at an angle of `37^@` with respect to the ground. Find the speed of the glider so that rain appears to him falling vertically. Consider the motion of the glider and rain drops in the same vertical plane.

A

`15ms^(-1)`

B

`30ms^(-1)`

C

`10ms^(-1)`

D

`25ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
Horizontal component of both should be same.
`ucostheta=v_("rain") cos45^@`
`impliesucos37^@=12sqrt(2)xx1/(sqrt(2))impliesu=15m//s`

To a man going with a speed of 5 ms^-1 , rain appears to be falling vertically. If the actual speed of rain is 10 m s^-1 , then what is the angle made by rain with the vertical ?

A man is standing on a road and observes that rain is failing at angle 45^(@) with the vertical. The man starts running on the road with constant acceleration 0.5m//s^(2) . After a certain time from the start of the motion, it appears to him that rain is still falling at angle 45^(@) with the vertical, with speed 2sqrt(2)m//s . Motion of the man is in the same vertical plane in which the rain is falling. Then which of the following staement(s) are true.
