The mass of each object is a multiple of the base 1 of co Attempts Macmillan Learning mass m: object 1 has mass 4.30m, object 2 has mass 1.96m, 3 Question 0% and object 3 has mass m. When the objects are at the bottom 0 of oo Attempts of the steps, define the total gravitational potential energy of the three-object system to be zero. If the objects are then 4 Question 100% relocated as shown, what is the new total potential energy of 1 of . Attempts Correct the system? Each answer requires the numerical coefficient to an 5 Question 100% 1 algebraic expression. Each algebraic expression is given 2 3 1 of o Attempts Correct using some combination of the variables m, g, and d, where g is the acceleration due to gravity.
