• A little boy is standing at the edge of a cliff 1000 m high. He throws a ball straight downward at an initial speed of 20 m/s, and it falls straight down to the ground below. At a time of 6 seconds after it was thrown, how far above the ground is it? The acceleration due to gravity is 10 m/s2 .
• Required Information: Problem 16.048 - Dependent Multi-Part Problem - Assign all parts. Note: This is a multi-part question. Once you submit an answer for a part, you cannot return to it. A uniform slender rod, AB, is on a frictionless horizontal surface. A force, P, with a magnitude of 0.25 lb, is applied at point A perpendicular to the rod. The rod has a weight of 2.2 lb. Problem 16.048.a - Determine the Acceleration of Point A on the Slender Rod Calculate the acceleration at Point A. You must answer this before proceeding to the next part. The acceleration of Point A is 14.6 ft/s². Correct.
