Arock thrown with speed 8.50 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. a second rock is thrown straight upward with a speed 4.250 m/s . if this rock takes 2.717 s to fall to the ground, from what height h was it released?
