An object O is just about to strike a perfectly reflecting inclined plane of inclination `37^(@)`. Its velocity is `5 m//s`. Find the velocity of its image.

A

`3(hat i)+4(hat j)`

B

`4(hat i)+3(hat j)`

C

`4.8(hat i)+1.4(hat j)`

D

`1.4(hat i)+4.8(hat j)`

Text Solution

Verified by Experts

The correct Answer is:
C

`v_(o)=5 m//s`
`v_(I)=(5 cos 16^(@)) hat i +(5 sin 16^(@))hat j`
`=(4.8 hati+1.4 hat j) m//s`.
