A ball thrown by a boy is caught by another after 2 sec . some distance away in the same level. If the angle of projection is `30^(@)`, the velocity of projection is

A

19.6 m/s

B

9.8 m/s

C

14.7 m/s

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
`T = (2u sin theta)/g rArr 2 = (2u sin 30^(@))/9.8 rArr u = 19.6 m//s`
