A ball falls freely from a height 
on a rigid horizontal plane. If the coefficient of restitution is e, then the total distance travelled by the ball before hitting the plane second time is
A
he 
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
As ball dropped from height 
, then it will strike the plane with velocity, 
. Now after striking the plane, it will bounce back with velocity, 
Now it will travel total 
distance before
Here 
So, total distance
