When a particle is thrown horizontally, ...

When a particle is thrown horizontally, the resultant velocity of the projectile at any time t is given by:-

A

gt

B

`(1)/(2)"gt"^(2)`

C

`sqrt(u^(2)+g^(2)t^(2))`

D

`sqrt(u^(2)-g^(2)t^(2))`

Text Solution

Verified by Experts

The correct Answer is:
C
`v_(y)=0+gt`
`v=sqrt(v_(x)^(2)+v_(y)^(2))=sqrt(u^(2)+g^(2)t^(2))`
