A small steel ball bounces on a steel plate held horizontally. On each bounce the speed of the ball arriving at the plate is reduced by a factor e (coefficient of restitution) in the rebound, so that `v_("upward")=eV_("downward.")` If the ball is initially dropped from a height of 0.4 m above the plate and if 10 seconds later the bouncing ceases, the value of e is

A

`sqrt((2)/(7))`

B

`(3)/(4)`

C

`(13)/(18)`

D

`(17)/(18)`
