The girl throws the 0.5-kg ball toward the wall with an initial velocity vA = 10 m/s. Determine

(a) the velocity at which it strikes the wall at B,

---

(b) the velocity at which it rebounds from the wall if the coefficient of restitution e = 0.5, and

---

(c) the distance s from the wall to where it strikes the ground at C.
