Learning Goal: To practice Problem Solving Strategy 4.1 for projectile motion problems. A rock thrown with speed 8.00 m/s and launch angle 30.0 (above the horizontal) travels a horizontal distance of d = 17.5 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. Find the height y, from which the rock was launched. Express your answer in meters to three significant figures. ▸ View Available Hint(s) 31= 15. ΑΣΦΑ Submit Previous Answers * Incorrect; Try Again; 3 attempts remaining m
