An object, M = 2 kg on a frictionless horizontal surface was displaced along + x-axis by d (41) m while a force F = (8i + 6k) N was acting on the object. Here, i and k are the unit vectors along the x and z axis, respectively. (a) Find the work done by F on the object during the displacement. What is the scalar product, F. d? (b) If the object start from rest, vi = 0, find it's kinetic energy at the end of this displacement. What is the work done by the gravitational force during this displacement? = An object, M = 2 kg on a frictionless horizontal surface was displaced along + x-axis by d (41) m while a force F = (8i + 6k) N was acting on the object.
