Ram moves with a velocity of 10m/s in west direction. Shyam moves a direction `23^(@)` East of North Ram is 100m away from Shyam it, direction `53^(@)` East of North of him.What should he speed of shyam so that he collides with Ram.

A

`4sqrt(3)m//s`

B

`10m//s`

C

`12m//s`

D

none of these

Text Solution

Verified by Experts

If Shyam has to cllide with Ram, the should hav velocity towards Ram in refrence of Ram.

`v_(s) sin 30^(@)=10 sin 37`
`v_(s).(1)/(2)=10xx(3)/(5)`
`v_(s)=12m//s`
