Two forces act on a 2.65 kg object, the gravitational force and a second, constant force. The object starts from rest and in 1.20 s is displaced (5.0M (Enter your answer in kg - m/sz. Assume the gravitational force acts in the j direction.) F = (18.40277778i 38.11583332j) x 3.30j) m. Write the second force in unit vector notation. a A First, nd the acceleration vector using kinematics, then substitute into Newton's second law to determine the unknown force vector. Recall that the gravitational force is Fg = mgj. kg - m/s2 Need Help? _ Submit
