Question

a small ball is dropped from rest from height 10m on a horizontal
floor if e between ground and body is 0 5 then find the max ht it
can rise after collision plz try to tell fast i hv a test tmrw
thankx!

Ansh S · Answer

velocity just before striking the ground = v = root(2gh) = root
(2*10*10)
velocity just after collision with the ground = v' = ev = 0 5 *
root(2*10*10)
max height => 0 - 2*10*10 = 2*(-10)*h => 10m
hope this helps
