Part A Two stones are thrown vertically upward from the ground, the faster stone 1 with three times the initial speed of the slower stone 2. Assume free fall. If stone 1 takes 10.0 s to return to the ground, how long will it take stone 2 to return? Express your answer in seconds. AEd to = Submit Request Answer Part B If stone 2 reaches a maximum height of A, how high (in terms of H) will stone 1 go? Express your answer as a multiple of height # using two significant figures.
