Two stones are thrown vertically upward from the ground, one with three times the initial speed of the other. Assume free fall. If the faster stone takes 11.0 s to return to the ground, how long will it take the slower stone to return? If the slower stone reaches a maximum height of H, how high (in terms of H) will the faster stone go?
