WebScience Physics University Physics (14th Edition) A student of mass 45 kg jumps off a high diving board. What is the acceleration of the earth toward her as she accelerates toward the earth with an acceleration of 9.8 m/s 2 ? Use 6.0 × 10 24 kg for the mass of the earth, and assume that the net force on the earth is the force of gravity she exerts on it. WebJun 7, 2005 · A diving board of length L = 3.00 m is supported at a point a distance 1.00 m from the end, and a diver weighing 490 N stands at the free end. The diving board is of uniform cross section and weighs 295 N. Find the force at the support point. Suppose F1 is the force applied at the support point and F2 is the force at the end that is held down.
