The only force acting on an object moving along x-axis is given by Fx = 5.6x, where x is in meters. If the velocity of the object at x = 0 is 2¹, and at x = 8.35 m the velocity is equal to 16m, find the mass in units of kg of the object. Please round your answer to 1 decimal place.
= 1.8 kg Consider a uniformly distributed massive lever of mass M and length L = 13.6 m with a fulcrum located at position R = 4.3 m from the left end of the lever. If a force of F₁ = 50.7 N is applied on the left end of the lever pointing down, then what force in units of Newtons must be applied on the other end pointing down in order to keep the lever balanced? Consider the acceleration due to gravity to be 9.8m. Please specify your answer to 1 decimal place. R F2 F₁
