Using Newton's 2nd Law Corcos Two tugboats are pulling a 4.2 x 10° kg barge into a harbour (Figure 3). The first tugboat exerts a constant force of 1.8 x 10° N [E 37° NJ. The second tugboat exerts a constant force of 1.3 x 10 N [E 12° S]. Calculate the acceleration (magnitude and direction) of the barge. Assume there is no friction acting on the barge. F, 37° 712
