The center of mass of a 0.3 kg (non-uniform) meter stick is located at its 46-cm mark. what is the magnitude of the torque (in nm) due to gravity if it is supported at the 25-cm mark? (use g = 9.79 m/s2)

suppose that a meter stick is balanced at its center(50 cm mark). a 0.27 kg mass is then positioned at the 20 cm mark. at what cm mark must a 0.30 kg mass be placed to balance the 0.27 kg mass?

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
