- A 392-kg boat is sailing 18.0° north of east at a speed of 1.90 m/s. 31.0 s later, it is sailing 35.0° north of east at a speed of 3.60 m/s. During this time, three forces act on the boat: a 32.6-N force directed 18.0° north of east (due to an auxiliary engine), a 21.1-N force directed 18.0° south of west (resistance due to the water), and (due to the wind). Find the the magnitude of , in Newtons.Two carts on a low friction air-track are connected by an unstretched spring. Cart 1 has an inertia of 1.5 kg while cart 2 has an inertia of 2.5 kg.
