10. Two forces act on a 3 kg object, the gravitational force and a second, constant force. The object starts from rest and in 2.1 s is traveling with a velocity of (20ˆi + 10ˆj) m/s. At what angle does the second force act with respect to the ˆi direction? Assume the gravitational force acts in the −ˆj direction. (the answer is 56.8 ◦)

Two forces act on a 3.20 kg object, the gravitational force and a second, constant force. The object starts from rest and in 1.20 s is displaced (4.251 - 3.301) m. Write the second force in unit vector notation. (Enter your answer in kg. m/s. Assume the gravitational force acts in the - direction.) = (18.888)i + (17.152); First, find the acceleration vector using kinematics, then substitute into Newton's second law to determine the unknown force vector. Recall that the...
