As shown in the figure a body of mass m moving vertically with speed 3 m/s hits a smooth fixed inclined plane and rebounds with a velocity v f in the horizontal direction. If angle of incline is 30°, the velocity V f will be
A
3 m/s
B
m/s
C
l/ 
m/s
m/s
D
This is not possible
Text Solution
Verified by ExpertsThe correct answer is:
B
Velocity along surface remain same 3sin 30° = v f sin 60°
