B. Both Rian and Lim threw a rock with the same shape and mass from a 60 m tall building to the ground. Rian threw her rock straight downward while Lim threw his rock downward and outward with an initial angle of 30° at 17 m/s. Solve the following problems: a. Final velocity after 6 seconds b. Time it takes Rian's rock to reach the ground C. Time it takes Lim's rock to reach the ground d. Which of the rocks will reach the ground first?
