Question

A ball is thrown at an angle of incidence 'A' ona
horizontal plane such that the incident direction and
the reflected direction are at right anlges to each other
if the coefficient of restitution is 'e' then 'A' is equal
to
a) Tan (e)
b) Tan-"(20)
c) Tan="(V2 e)
of Tan"(Ve)​

Answer 1

Answer:

tan (e)

Explanation:

it is because the coefficient of restitution is E and is equal to N and p
