1. The problem statement, all variables and given/known data A 3.7 kg mass has a constant acceleration from an initial velocity of 2.33 ihat m/s to a final velocity of (18.9 ihat - 10.7 jhat) m/s in 2.71 s. Two forces act on the mass: gravity and an unknown applied force. Determine the acceleration and unknown force. 2. Relevant equations 3. The attempt at a solution For the acceleration i managed to get 16.25 m/s, and for the force of gravity it is -36.26 m/s.
