A car is travelling in steady rain with constant acceleration in a straight line When is begins to move the driver sees that the raindrops make track at an angle of `37^(@)` with the vertical on the side window. After 20 sec., the raindrops make track at an angle of `53^(@)` with vertical in same direction Find the acceleration of the car in `cm//s^(2)` Rain is falling at `3 m//s`.

Answer

`0007`

Explanation

`(3V)/5=12/5`
`V=4`
`(4V)/5=9/5+V_(c)=7/5`
`V_(C)=0+a_(C) t`
`a_(C) =7`
