Two forces act on a 3.75 kg object, the gravitational force and a second, constant force. The object starts from rest and in 1.20 s is displaced(4.35î − 3.30ĵ) m. Write the second force in unit vector notation. (Enter your answer in kg · m/s2. Assume the gravitational force acts in the −ĵ direction.)F =kg · m/s2
