You are given a four-wheeled cart of mass 14 kg, where the distance between a wheel and its nearest neighbors is 2.0 m. Suppose we load this cart with a crate of mass 102 kg, where the crate's center of mass is located in the back-middle of the cart, 0.500 m from its center.(a) Find the weight on the nearer wheels of the cart under this load.(b) Find the weight on the farther wheels of the cart under this load.
