A ball is thrown horizontally from a point O with speed 20 m/s as shown. Ball strikes the incline along normal after two seconds
The speed of ball just before striking the plane is:

A

20 m/s

B

`20 sqrt2 m//s`

C

`20 sqrt5 m//s`

D

none

Text Solution

Verified by Experts

The correct Answer is:
B
Speed of the ball, `V_(H)=20m//s to ` No acceleration in horizontal
`V_("vertical")=g xx t to 20m//s, V-sqrt(V_(H)^(2)+V_(V)^(2))=20sqrt2`
