A rock thrown with speed 12.0 m/s and launch angle 30.0 ° (above the horizontal) travels a horizontal distance of d = 20.0 m before hitting the ground. From what height was the rock thrown? Use the value g = 9.800 m/s² for the free-fall acceleration. Part D A second rock is thrown straight upward with a speed 6.000 m/s. If this rock takes 1.925 s to fall to the ground, from what height H was it released? > View Available Hint(s)
