Two forces act on a 2.50 kg object, the gravitational force and a second, constant force. The object starts from rest and in 1.20 s
is displaced (5.50î – 3.30j) m. Write the second force in unit vector notation. (Enter your answer in kg · m/s. Assume the
gravitational force acts in the -ĵ direction.)
